Um . . . every book I've ever read!
I'm something of a night owl so it's not uncommon for me to still be awake at two in morning with my kindle in my hands and my mouth drooling on the pillow.
I guess the last book that kept me up just dying to know what happened next was Thoughtless by S. C. Stephens you can read my review on my other site Book Me! This was one of those books that I adored and hated all at the same time! Oddly enough, I'm always super excited to write the reviews for the books that create those sorts of conflicted feelings within me, as I literally can not shut up about them.
Another book, and this is going back a few months now, that had me sitting up until some ungodly hour was Rhiannon Frater's The First Days (As the World Dies)
That baby was all suspense, all the time!
