A pretty riveting thriller, I liked this one quite a bit more than Jensen's The Sister. In The Gift, a heart transplant recipient seems to be receiving memories and messages from her donor. In her quest to figure out what her donor wants from her, Jenna grows more and more obsessed with Callie's life, to the detriment of her own. 
 This definitely kept me turning the pages, but the ending was a bit of a mess. It didn't make much sense, and since there wasn't much in the way of clues about any of it before hand, it felt manipulative and contrived. It seems like every character in the book was hiding something, and all the secrets were linked, which struck me as too farfetched to be believable. 
 Still, the concept of cellular memory and a recipient receiving messages and memories from a donor is an original one, and it was an enjoyable read. If the ending made more sense, I'd have given it five stars.
