A genetically modified vampire wakes up with amnesia and knows just one thing: that she and her family have been hunted. Is she the only survivor? Who are her enemies? What type of monster is she? Borrowing tropes from murder mysteries, thrillers, courtroom dramas, vampire novels, and science fiction generally, it really seems like this book is trying to do too much. But as the last book Butler published before her death, she is at her absolute best, balancing each element to perfection while offering a captivating mediation on identity, race, and free will. Octavia Butler was truly in a class all her own.
