Invasion, the first novel in M.R. Forbes's Forgotten Vengeance series, opens with a premise stripped to its essential tension: two hundred years ago, aliens invaded Earth, and humanity split between those who fled to Proxima and those who remained in the ruins. That divide has calcified into two profoundly different civilizations, one advanced and peaceful, one broken and savage. Now a new threat is coming, and neither branch of humanity can survive it alone. This audiobook, narrated by R.C. Bray, moves through that setup with the kind of velocity Forbes is known for, and Bray's multi-character narration is the element that keeps a six-POV novel from feeling chaotic.
The Verdict, Briefly
Forbes builds his ensemble with deliberate variety: a Sheriff, a Marine, a Pilot, an Engineer, a Centurion, and a Clone. Each POV carries its own register, and one of the genuine craft achievements of the novel is that the characters feel distinct rather than interchangeable. The Sheriff and the Centurion operate in very different emotional registers from the Marine and the Pilot, and Forbes maintains those differences across POV switches without slowing the momentum. Reviewers consistently flag the unexpected twists and developments alongside the fast pacing, and the cliffhanger ending is described as solid rather than gratuitous, a setup for the rest of the Forgotten Vengeance series rather than an artificial suspension.
The central premise, the Proxima survivors and the Earth survivors must eventually collaborate against an extinction-level threat, is not a new shape in military science fiction, but Forbes executes it with enough specificity that the familiar architecture does not feel like a limitation. The new invading force, described as a hunger that has swallowed half the universe, arrives as a third variable that disrupts the simpler Earth-versus-Proxima dynamic and forces the characters into unlikely alliances. The plotting is tight for a multi-POV novel of this scope.
Why Invasion Works as an Audiobook
R.C. Bray is one of the more reliable narrators in military and science fiction audio, and his work here earns the trust listeners bring to his name. He handles six distinct character voices without flattening them into the same register, which matters enormously in a novel where the emotional stakes of each POV are meant to feel genuinely different. His pacing is well-calibrated, fast enough for action sequences to have kinetic urgency, deliberate enough in character moments that the human stakes land.
One reviewer noted a particular affection for Caleb, and Bray's rendering of that character is likely part of why that response is so consistent across the fan base. The wormhole galaxy section of the novel generates significant reader attachment, and Bray's handling of those passages has the warmth that makes character investment stick across a multi-book series. For listeners planning to continue with the Forgotten Vengeance series, this first audiobook establishes Bray's template for the cast in ways that will pay dividends across subsequent volumes.
Points to Consider
One caveat from an experienced Forbes reader is worth noting honestly: editing quality in the text has been flagged. One reviewer describes needing to reread sections to determine which word was actually intended, citing what appear to be homophone substitutions and spell-check-introduced errors. In audio, Bray reads what is on the page, and a narrator of his caliber will deliver an unclear sentence cleanly, which means listeners may occasionally need to rewind and re-listen to parse what the intended meaning was. This is a text-level issue, not a narration problem, but it is worth flagging for listeners who find this kind of error disruptive.
The novel also sets the stage for a series rather than concluding its own arc, which is standard for the genre but worth stating plainly. Invasion is a series opener. The cliffhanger is real. Listeners who prefer self-contained narratives will want to check whether they are comfortable committing to the Forgotten Vengeance series before beginning, since the investment in characters and setup pays off across multiple books rather than within this one alone.
A word on M.R. Forbes as an author for listeners who are new to his work: Forbes is genuinely prolific across multiple science fiction subgenres, with a catalog that spans military sci-fi, LitRPG, and space opera. One reviewer noted looking through Forbes's website and finding many additional series that looked appealing, alongside a concern that the tropes of hero-versus-alien-invader might feel repetitive across the catalog. That is a fair observation for listeners who plan to read widely in Forbes's output. Within the Forgotten Vengeance series specifically, Invasion establishes its characters strongly enough that the familiar genre architecture feels grounded rather than generic. Whether that holds across the full series arc is a question subsequent volumes answer.
The audiobook's runtime of just over 9 hours is a reasonable commitment for a series starter of this scope. Forbes does not pad the novel, and the six-POV structure means the narrative never lingers too long on any single character before the next section begins. For listeners who find single-POV military sci-fi too claustrophobic, Invasion's ensemble approach is a genuine structural advantage.
Who Should Listen to Invasion
Military science fiction listeners who enjoy multi-POV ensemble casts, humanity-versus-alien-threat premises, and the kind of rapid plotting that Forbes has made a signature will find Invasion highly rewarding. Fans of R.C. Bray who want to hear him work with a large character roster should seek this out. Listeners who enjoyed Forbes's other series or ensemble-driven military sci-fi in a similar vein will recognize the pleasures on offer.
Approach with realistic expectations if minor text-level errors create friction for you in audio. The story is strong and Bray's performance is excellent, but the underlying text carries the marks of under-editing. For most genre listeners, this will not outweigh the novel's considerable momentum.
In Brief
- Read by: R.C. Bray is the ideal engine for military sci-fi of this velocity, and his handling of multiple POVs is clean and propulsive throughout.
- At its heart: Survival across divided humanity, alien threat convergence, ensemble heroism
- Vibe: Fast-moving and action-driven, with a multi-character structure that keeps the momentum varied
- Short version: A strong series opener for military sci-fi listeners who want rapid pacing and a large-cast ensemble, with Bray's narration turning an already fleet-footed novel into something close to compulsive listening.
Is the Invasion audiobook the start of a series, and do I need to read anything first?
Invasion is book one of the Forgotten Vengeance series by M.R. Forbes, so no prior reading is required. It does end on a significant cliffhanger, meaning the story continues in subsequent volumes rather than resolving fully here.
Does the Invasion audiobook have any production or narration issues worth knowing about?
The narration itself is strong, but the underlying text has reported editing issues, including apparent homophone substitutions and unclear word choices in some passages. Bray reads what is on the page, so listeners may occasionally need to rewind to parse an unclear sentence. The issue is in the text, not the performance.
What other audiobooks would appeal to fans of Invasion by M.R. Forbes?
Listeners who enjoy this one tend to gravitate toward other large-scale military sci-fi series with R.C. Bray narration, including his work on Dennis E. Taylor's Bobiverse series, or multi-POV alien invasion narratives from authors like John Scalzi and Jason Anspach.
