1.5 Stars. If you've ever known the ending to any episode of CSI (insert city of choice name here) or an M. Night Shyamalan movie do not - I repeat DO NOT - read this. There were ZERO twists and turns and the ending was completely predictable. Total bummer. I'm glad I read fast so at least I only wasted one day of my life. Finding out I knew what was happening all along after plowing through Christine's journal and her daily recap of figuring out who she is/why she's older/who she's waking up to (à la 50 First Dates), I was ready to punch someone in the throat. If you want to go on a trippy psych-thriller voyage choose Gillian Flynn. At least if you figure out the ending she'll take you on a wild ride to get there.
