Okay, so this was a WEIRD book. I liked it, but it was WEIRD. Jack's mother was kidnapped at age 19 and has been kept in a room ever since. (Yes, she had a child with her kidnapper). Jack is just turning five in the start of the book, and the book is told from his point of view. Jack has never been outside the room. Everything in the room is like a sentient being.. Table.. Chair.. Bed.. Wardrobe (where he sleeps). Spoiler alert!! Jack and his mother escape and have to acclimate to the Outside.
As I said, it was REALLY weird, but yet again, I really liked it. I just wish there was more. I want to know what happens AFTER, yanno? So, read it, and be prepared for weird :D
