The preview starts like a fun and happy story - one I definitely would want to read (I'm providing a time travel plot in my head, and that sounds like a fun story). On the other hand, the blurb and other reviews suggest a story that will make me cry - I'm not a fan of those types of stories. The cover and title made me think it was some sort of thriller/suspense novel. So lots to like at the outset, but other reviews have made me wary.
