4.5 stars 
 If you've made it this far in the story, you have to see how it turns out. This whole series is one long high speed chase! Highly, highly recommend this series. 
 I gave it 4.5 stars because it could have ended without the epilogue (and the rest explained in the spoiler below), or the epilogue could have flashed forward just a few years after the events of the book to give closure to other loose ends. 
 (view spoiler)[I felt uneasy that the reason they experienced recurrent memory loss was because the universe didn't want them to break up. I would have bought into the idea that it was brought on by voodoo because Shrimp's mom was jealous or needed revenge. Despite that, I thought the Silas/Charlie story was really sweet. I do love these two characters, each flawed but together they are magnetic! Oh, and the way Silas made her fall in love with him again? Swoon! (hide spoiler)]
