'til Death

This second book (first was Prisoner of Circumstance) by Nadine Zawacki also uses the Brooklyn settings with which she is familiar, but in this one she brings the Biblical story of Hosea up to the modern day. Here is her description of the story:
"Sal Martinelli grew without his mom and the last thing in the world he wanted for his son was to grow up without his, but Vickie Martinelli wasn't your typical mother. She was and continued to struggle with a life of drugs and all that comes with that. Sal loved his wife even though he wasn't sure she loved him. He continued to honor the vows he made 'til death do us part.
What happens when a past love comes back into Sal's life? Will that make a difference? 'Til dealth do us part . . . aren't just words, but a promise."
