This book is probably one of the most difficult books I've ever tried to review. It's so hard to categorize it and there is absolutely nothing out there like it. We see the world through five year old Jack's eyes, and it's remarkable how Miss Donoghue manages to depict this. Jack is so believable and so heartbreaking. Jack's Ma had been kidnapped when she was 19 and held in a small (11'x11') sound proofed shed for 7 years by a man we only know as Old Nick. She never sees the outside except through a sky light. And she has Jack two years after her abduction. We come into the story when Jack is 5, but we see what his world is like in this prison. To her credit, Jack's mom provides as much stimulus as she can for him and as a result, Jack is a very intelligent little boy that knows how to count, read and write. She manages to create a world for him that is safe and wonderful from within the confines of this room. The last half of the book is all about Jack and his Ma's life outside, and I think that this part is even more sad and poignant than the first part because everything is so new and scary for both of them, and they each have a huge adjustment to make while living life outside of Room. But we have Jack's perspective of everything throughout this wonderful book, and that is a special thing indeed. I think it made me even look at things differently in our big old world. Above all, this book is not sad, but it is poignant, profoundly affecting, and a book that depicts love like no other book I've ever read. I am glad I took the time to read it.
