My latest read is Joan Didion's "The Year of Magical Thinking."
In the book, Didion addresses the trauma she faced after the coma of her daughter and the sudden death of her husband.
While the book has nothing to do with infidelity, I was touched by how Didion faced (or avoided) triggers and how she tried to be in control and "normal" when in hindsight she was anything but.
Those who have dealt with an S or D may find Didion's "Magical Thinking" about her H coming back (she couldn't give away all of his shoes) powerful. (I never moved my H's slippers or bathrobe during our S.)
An A isn't death, but I think there are some issues in this book that many A "survivors" can relate to.
