While I was writing the review for The Sea Thy Mistress, I asked for suggestions of books that deal with extreme emotional pain. At least one of the answers was facetious, but all in all, there are some good suggestions below, including one that was for a very bad handling that my husband thought no one should read.
The Mountain and the Valley by Ernest Buckler (this was the one Bill said no one should read)
everything by Elizabeth Bear
Good Grief (not sure of the author)
Harry Potter and the Order of the Phoenix by J.K. Rowling
A Tale for the Time Being by Ruth Ozeki
The Hours by Michael Cunningham
Memory by Lois McMaster Bujold (and all the Miles books)
The Felix Castor books by Mike Carey
I Miss You, I Miss You! by Peter Pohl
Any suggestions for other books to add to the list?
