This would have been written in late 80s or early 90s. Tells the story of a family whose son committed suicide by hanging. After his death the parents take in a foster son who is the same age as their son. He begins taking on the late son’s identity. I am almost certain one of the character’s names was Solomon. The dad is searching for answers about his son’s death and finds the boy’s computer password under the keyboard and I think he discovers the mom was secretly abusing the son.
Thanks for any help in figuring this out. It’s been driving me bonkers for years.
