Sweet but thought-provoking little book. However, I don't think it's nearly as deep as it thinks it is, or at least, sets out to be. It's a quiet book, with few characters or plot action as it is mostly concerned with the philosophical and theological conversations taking place between Cecelia and Ariel. Ariel is an angel and Cecelia is an 11 year old girl who has terminal cancer. The problem for me is that Cecelia really doesn't sound like an 11 year old - more like an author trying to sound like an 11 year old. The age-old age problem! And so the book rings false in my ears.
