by Jessica Brody This is the second book in the Unremembered trilogy, although I have not read the first one. I still felt like I knew what was going on, though, and Unforgotten stands pretty well on its own. It started out strongly, with Seraphina and Zen living in 1609. Due to a technological advancement in the nearish future, both Seraphina and Zen have a gene that allows them to travel through time. Seraphina was created by a company called Diotech, so she has enhanced physical abilities. In the previous book, she had escaped from Diotech, and they now desperately want her back, so she is careful not leave any trace of her identity that Diotech would be able to use to find her. The time travel aspect was done well, although I wish some parts of it had been explored a little more. I also liked the main plot. It was engaging, interesting, and gave you enough information without giving too much away....
