I finished this book in two days. It was very accessible, easy to fall in love with the falty characters, and written very well. Have I said this before? I'm jealous of mystery writers.
"Paris by the Book" by Liam Callanan engrossed me. I read the whole 300 some pages in two days. While working a part time job and going to class. Ask me if I've slept, seriously ask me. I haven't.
