The Demon's Lexicon (The Demon's Lexicon, #1)
I got drawn into this story so much and I loved the characters...and oh my goodness the twists and the turns (many unexpected) just kept me guessing and left me gasping with disbelief. I have rarely hated distractions and interruptions so much but I just didn't want to put this book down.
If you want a roller-coaster of a read where you are constantly stuck to the back of your seat...this is the book to read!
