I debated between 2 & 3 stars for this one and finally decided on 2. The tale ended up so convoluted and all over the place. So many things didn't line up with my perception of how time travel would work. Just too much that was one way on one page and another way on the next. The only character I cared about at all was Finn. Marina, or Em, and James could both rot. I'm wondering how a 2nd book would work, but it really doesn't matter as I won't bother with it anyway. Bit of a waste of time.
