Nothing about In The Blood is what it seems. Nobody is who you think they are. You want an unreliable narrator? Main character Lana Granger isn’t even sure she herself is telling the truth. It isn’t until you’re about three-quarters of the way through the book that you realize how cleverly Lisa Unger has obfuscated things with the use of simple pronouns.
Quite simply, this book is genius. Read it. And then read it again, slowly, now that you know the ending. It’s worth it.
