5 holy [filtered]ing stars! 
 Plus all the stars in the 'verse. This book blew me away. It was funny, surprising in the BEST ways possible, romantic in the way that makes your heart have 7-minute bursts of squeals and happy dances, satisfyingly creepy and chilling, and just plainly [filtered]ING AWESOME. 
 Definitely one of the best I've read this year (and maybe even a decade). No bull[filtered], that's how good this book is.
