***This is a review of the audiobook***
I love Beck's stories, and this is a fun installment in his creature books. It reminds me a bit of his "Center Of The Earth" series, and there is definitely crossover in the themes. There is some crossover in the capabilities of the monsters too, but I can't say much more about that without venturing into spoiler territory. I agree with some of the reviews that Troy is pretty feeble as a spy character-- that whole angle feels like a missed opportunity. The villains in this one are frightening and manipulative, but mostly two-dimensional though. Still, their motivation drives the story into very uncomfortable places and keeps the stakes extra-high. There is also a massive and surprising twist at the very end I didn't see coming. The narrator, Sean Mangan, is excellent as always, though I sometimes find his pronunciation of words and his diction a bit strange. Example: Instead of "skel-e-tal," he says "skel-EEE-tal," which is odd, but that's how he rolls! Still, he's perfect for this story, and I've come to associate his soothing voice with Beck's writing. If Beck were ever to choose another narrator, it would just be weird at this point.
In general, the characters aren't the most developed, yet despite that, this book is a fun adventure of exposition and history. In other words, it's an entertaining listen that lacks meaningful substance. Lest this sound like a back-handed compliment, let me reiterate I did enjoy this book very much. Compared to other books from this author though, I don't see myself going back for seconds. "Fathomless," and its sequel, "Abyss," are so powerful that I've listened to each at least six times, and will probably do so again. Those books are fantastic, rich with intrigue, and outstanding character development. This one doesn't have that same attention to character at all. Still, it's a wild enough adventure to which I couldn't stop listening, if only to find out what happened next. The monsters are terrifying, the premise is outstanding, and I love historically-based adventures. I love creature features even more.
One thing that keeps the story moving (and this doesn't always work in books) is a past-present device where the story goes back in time a thousand years, foreshadowing events to come, then returns to present-day. Beck does this sometimes in his other stories too. There is also the noted influence of Jules Verne, as in the "Center Of The Earth" series, which is a fun callback to those books. "Lemuria" also leaves us with an unexpected cliffhanger, so I am now excited for the sequel to come out!
