This character guide covers arcs across the whole book and may contain spoilers.

This novel has a big, busy cast anchored by Caroline Black, a bakery owner hiding from her past, and Knox Mars, the protective local who digs into it. Around them are the Mars family, bakery staff, townspeople, and the Costa crime family, so the story mixes small-town warmth with real danger.
