Entertaining and suspenseful. For the main portion of the book, I couldn't help but think, "Kate's in a dream-trance/astral projection state. How is she able to do all this crap? did she suddenly develop a talent for teleportation and if so - why isn't this, like, an amazing thing?!" If you can ignore this HUGE plot hole, then the book is quite entertaining and fun. I'd love to know more about this world and sometimes wish Michelle would've expanded more in her detail, but I had a lot of fun with this book.
