This HaBO comes from Jacqueline, who is looking for a darker contemporary or possibly romantic suspense:
Been trying to find this one after I deleted it from my kindle; it’s long gone.
Couple meets when her father (abusive murderer) married his mother (sweet wealthy lady who dies sometime later, I wonder how…). They date in college but he gets put in jail I think (?) by evil (step)father of heroine.
Hero ends up taking back family business and winning back heroine, book ends with them opening a mechanic shop (going for the quiet lifestyle this time around) and eating macaroni and cheese on the couch.
Well that’s a sweet ending!
