About This Audiobook

Parker Ferro owes the fae his life. They’ve come to collect.

When the Summer Queen summons Parker to her court, the private investigator knows there’s trouble brewing. Trapped into compliance by his past debt, he’s tasked with locating a missing girl in San Amaro. Now he has to find the girl or give up his life.

Things only get more complicated when a very familiar cop asks Parker for his help on a case involving murdered magic users. With the victims completely drained of their magic, the San Amaro Police Department needs Parker’s special skill set to track down a killer. Navigating through San Amaro’s paranormal underbelly while dealing with his own past and this new case is the last thing Parker wants or needs.

Now Parker’s stuck trying to locate a missing girl, stop a paranormal war, find a killer, and resist Detective Nicholas King’s many charms. Here’s hoping he doesn’t die trying.

Wormwood Summer is a 107,000-word MM urban fantasy with a HFN ending.

Key Details

  • Performance: Greg Tremblay is the sole credited voice for a cast running from fae royalty to a city police squad.
  • What it covers: A life owed to the fae, a missing-person case, magic drained from bodies, a slow-building attraction across a case file
  • Feel: Noir with glitter on it, tense without turning grim
  • Our call: A capable first case with a romance that earns its space, on a record that cannot say where the series starts.

How much of a series is a first volume allowed to assume you already know? That question hangs over this audiobook from the opening chapter, and the record itself cannot answer it. The series field says San Amaro Investigations, book one, and the reception printed underneath disagrees in capital letters. Eleven hours is a long time to spend wondering whether you started in the wrong place, so it is worth sorting out before you press play rather than three chapters in, when the references to things you have never heard of start piling up.

How Wormwood Summer Holds Up

Parker Ferro owes the fae his life, and the Summer Queen has decided to collect. That debt is the engine: summoned to court, pushed into compliance, the private investigator gets sent to find a missing girl in San Amaro on pain of forfeiting what he owes. Then a second case arrives from a very familiar police detective, Nicholas King, involving magic users found drained of their magic. Two investigations, one city, a paranormal underbelly with four fae courts inside it, and a protagonist trying to keep his own history from surfacing. The construction is old-fashioned detective fiction with the supernatural bolted on where the corruption usually goes, and it holds.

Five written responses sit underneath a rating counter that reads one. That is not a rounding quirk or a lag in the display. A single vote can only be a whole number of stars, so the 4.5 on the badge cannot have come from one rating no matter how the arithmetic is arranged, and five people have clearly gone to the trouble of typing. The likeliest explanation is that the counter and the response feed are pulling from different editions of the same book, which is common on self-published records where the print, digital and audio versions live at separate addresses. Read the badge as decoration and the responses as the actual evidence.

Why Wormwood Summer Works as an Audiobook

Fae politics, a police procedural and a romance are competing for the same eleven hours, and a June 2025 write-up scores two of them with unusual precision: three out of five for the mystery, three chili peppers out of five for the heat, both higher than that listener had expected from a first installment. Those numbers are a better guide than any blurb. The crime plot is solvable if you are paying attention. The romance between Parker and Nicholas is not incidental and does not stay chaste. Anyone treating this as a clean detective story with a mild subplot has misread which half is load-bearing.

Greg Tremblay performs the recording, and the one write-up on the record that addresses the audio at all comes from a listener who reached the seventh book and then came back to say the series recordings are performed spectacularly, singling out something specific rather than general: every character gets a distinct voice and personality, including across the male and female split that so often collapses in single-reader productions. That praise covers the run rather than this volume alone, so treat it as a reason to sample rather than a guarantee. It is still the most concrete listening evidence anywhere on the page.

Weak Spots in Wormwood Summer

Series order is the real hazard, and the record is no help. A May 2022 write-up, awarding five stars while doing it, describes stumbling badly through the opening because the two leads clearly have a shared history the book never explains, and warns other readers off starting here. The listing insists this is book one of San Amaro Investigations. Both things can be true at once if the characters carry over from somewhere else, which is exactly what that response concluded. Nothing in the description, the series field or the categories acknowledges the possibility, and a buyer has no way to check it from this page.

Spice and structure aside, the worldbuilding is the recurring complaint. A May 2021 write-up, awarding four stars and praising the fae angle and the internal conflict between Parker's human and fae halves, withholds the fifth star precisely because the world is never elaborated: the reader gets dropped in and has to assemble the politics from overheard interactions. A January 2026 response reads the plotting more generously, calling the twists enough to keep it guessing without being complicated. Both are describing the same book. It moves quickly and explains slowly, which suits some listeners and irritates others.

The Right Listener for Wormwood Summer

Urban fantasy listeners who want the case to matter as much as the courtship are the target, and this delivers on both without letting either collapse into wallpaper. The description promises a hopeful ending rather than a permanent one, which is the right expectation to set for a series opener in a run that has since reached at least seven books. Anyone who enjoys a protagonist boxed in by an obligation he cannot refuse, working a case for people who own a piece of him, will find the setup does most of the tension work before any villain shows up.

Newcomers to the author should hold off until they have checked what else exists with these characters in it, because the loudest warning on this record is about exactly that. Hold off too if a police detective as love interest is a hard limit for you, since the attraction to Nicholas King is threaded through the case rather than parked beside it. The description flags the length in words rather than hours, a leftover from the print listing that tells an audio buyer nothing useful. Wherever you begin in this world, begin with the sample and a search for the character names.

A Few Questions About Wormwood Summer

Do I need to hear another book before this audiobook?

The listing calls it book one of San Amaro Investigations, but at least one reader concluded the leads carry a history from elsewhere and advised against starting here. Nothing on the page resolves it. Searching the character names before you commit eleven hours is the cheapest insurance available.

How explicit does the romance get?

Warmer than a first installment usually runs. One listener rated the heat three chili peppers out of five and noted it exceeded expectations for an opening volume. The relationship is threaded into the investigation rather than sitting beside it, so skipping those chapters means skipping plot.

Does the audiobook hold up as a mystery?

Partly. The crime plot is solvable, and anyone who reads detective fiction regularly will be ahead of the reveal. The pleasure is less in the puzzle than in the paranormal machinery around it: four fae courts, drained magic users, and a private investigator whose debts complicate every question he asks.

Intense yet a beautiful world

I loved the main character and how the author tackled the fae angle. It was unique and engaging reminding the reader of the internal conflict. Be human or give in to his fae nature.The only thing keeping it from a five star for me is the lack of really, elaborating...

DON’T READ THIS FIRST!

One of my biggest pet peeves is when series are released out of order or when authors don’t tell you what order to read their books in. THIS IS NOT THE FIRST BOOK IN THE SERIES. I tried to read this first and kept stumbling and getting confused because there’s...

Finished them all!

I just finished the 7th book so here I am to write a review. First I listened to the audio books, and they are performed spectacularly! I really hate it when a voice actor isn’t good at differentiating the characters, especially male and female, but that was not the case...

★★★★☆

surprising find

I am an absolute sucker for crime magic drama with dashes of romance and the fae. This one delivers on all fronts. Did I guess who the criminal was pretty early? Yup. So it’s about three who-dun-its out of five as far as mystery goes.Is there spice? Why yes, actually...
