This book works on many levels. It's not for people who are looking fur a brainless read. Nor is it intellectual or literary fiction. It is extremely realistic, totally engaging, and very satisfying. The characters are authentic and totally believable.
The story itself is brilliant. To quote another reviewer "this book sings."
I've read over 100 books in the last couple of years, and the only other one in the same league as this (in my opinion) was a Pulitzer Prize winner.
