I'm reading an unusual book

Here is the Amazon review:

In many ways, Jack is a typical 5-year-old. He likes to read books, watch TV, and play games with his Ma. But Jack is different in a big way--he has lived his entire life in a single room, sharing the tiny space with only his mother and an unnerving nighttime visitor known as Old Nick. For Jack, Room is the only world he knows, but for Ma, it is a prison in which she has tried to craft a normal life for her son. When their insular world suddenly expands beyond the confines of their four walls, the consequences are piercing and extraordinary. Despite its profoundly disturbing premise, Emma Donoghue's Room is rife with moments of hope and beauty, and the dogged determination to live, even in the most desolate circumstances. A stunning and original novel of survival in captivity, readers who enter Room will leave staggered, as though, like Jack, they are seeing the world for the very first time. --Lynette Mong

So far I'm enjoying it very much. The language goes far to capture the outlook of a five-year-old boy. The premise is disturbing, but I'm very interested to see what Donoghue does with it. I'll review it here when I finish. It just came out last month. It's not the type I would normally read, but I stumbled across it a day or two after it was published and it sounded intriguing.
