I've seen a few books floating around with that title, honestly. The most talked-about one I can think of is usually a classic contemporary romance setup. A protagonist, often someone who's made a big mistake or carries a heavy secret, returns to their hometown or a place from their past. They're usually running into an old flame they wronged. The whole plot revolves around them trying to make amends, proving they've changed, and navigating all the simmering resentment and unresolved feelings. The 'redemption' part is them earning back trust, not just from the love interest but often from the whole community. It’s pretty heavy on the angst and emotional payoff.
I read one last summer where the main character was a former lawyer who’d tanked a case that hurt the town, came back as a carpenter trying to rebuild literally and figuratively. The love interest was the sister of the person he’d failed. It followed that pattern pretty closely—slow burn, lots of conversations on porches at sunset, that sort of vibe. If you're into that particular flavor of second-chance romance, it’s probably the one you’re asking about. The specifics vary, but the core is always about healing a broken past.
