Room by Emma Donoghue
To 5-year-old Jack, Room is his entire world. It is all he knows. Any more than that gives the book away, but think Jaycee Dugard. This book was really good. I will admit the first 60 pages were a little hard to get through, but after that I could not put it down. It was just a little hard reading the book from the perspective of a 5-year-old. But actually that makes the book what it is. I highly recommend.
