Solid Near Stand-Alone Sequel Will Be Divisive. This is one of those books where a co-author was added… and makes an immediate and obvious impact. How you like that impact will likely depend on your own politics and worldview. Making one character from the previous book explicitly LGBT in this book – when this character’s sexuality was never discussed in the previous book at all – is a choice. As is adding in a nonbinary character, introducing them with pronouns, and then explicitly saying of an older character that this older character “needed to get it together”. Allegations that this book curses more than the prior book, as some 1 and 2 star reviews make, are unfounded, however, as Extinction (Book 1 of this series) actually has *more* uses of “fuck” or its derivatives than this book does, per searching the text of both books.
Then there is the religious side. The description of the book mentioning “relics” in connection to “Christendom” makes it clear that this book will have something to do with the Catholic Church. What it doesn’t prepare you for is how much of the darker aspects of the Church this book portrays. Again, some will enjoy this, others will want to defenestrate the book over it.
Divisiveness aside though, and read more as a standalone in-universe sequel with the barest of connections to the first book, for what it is this book is actually a solid mystery that eventually veers into the scifi, with action more a secondary concern and only in small doses. Nowhere near the intense action sequences of the previous book in this series, but also not really that far from Douglas’ earlier work in the Pendergast tales in particular. If anything, Pendergast fans will find a fair amount of that series’ obsession with the grotesque also makes a heavy appearance here.
And then the epilogue. Without saying *too* much, let’s just say that Douglas’ Author Note at the end reveals the title for Book 3, and that title for Book 3 combined with this tale and its epilogue? Don’t let the divisive nature of the co-author’s additions to the story here make you miss out on either story. This one was solid and interesting. The next one promises to be explosive.
Overall a solid tale that continues its series in unexpected yet interesting directions, one that will be divisive for many reasons both earned and unearned, yet ultimately one that does its primary job well in setting up the *next* book.
Very much recommended.
