I just finished An Exact Replica of a Figment of my Imagination and I really enjoyed it and would recommend it to those of you who haven't read it yet.
It is a memoir of someone's own experience after the loss of their child. It is honest and painful to read at times because I could relate to the experience. She wrote so eloquently about things that I too had experienced or that I am currently experiencing. Just a heads up that she does mention her rainbow in the book too. I found it to be one of the better books that I have read relating to child loss.
