The Riverboat Company by Florentina Riza

"It's such a weird to view it as a redemption arc makes it really awkward to like you," says author. "You almost have to ignore that that was the last relationship that he was in for this to be redemptive of him at all" The book follows Florentina riza and Adaza who discover each other on a riverboat after her husband's death. They are sailing past symbolism about how you can't go back, but then people start lining up to get on board because they've been flying cholera flag. When health officials come asking questions their brilliant strategy is to turn the boat around and fly the flag again.
