Letters for Scarlet - Julie C. Gardner
We learn about two women who used to be best friends - their present day and the letter that dredges up old memories.

Corie Harper has forgotten all about the graduation letter she wrote in high school. She spent the last ten years trying to forget about her best friend and the things that tore their friendship apart.

Scarlet Hinden is haunted by memories of Corie and what happened one night ten years ago. Now pregnant, Scarlet is convinced she would be a terrible mother and that she does not deserve the love of the father of her child.

There's nothing wrong with the writing. The book started off fine, but it became boring and the ending was anticlimactic. It's a forgettable book for me.
