The Lighthouse She Left Behind. Harborlight Secrets, #1

Mara Bellweather never meant to come home to Harborlight Cove with her four-year-old daughter in tow, not to the salt-stung village that remembers every heartbreak, every slammed door, every girl who left before dawn and never explained why. But when her aunt Ruth collapses and Bellweather Light begins to crumble at the mouth of the harbor, Mara returns to the peeling keeper's cottage on Gull Point carrying sketchbooks, guilt, and the one truth she has guarded with her whole life: Lila belongs to the man Mara once loved and left behind.
Finn Calder still works the dawn tide from Slip Six, steady as granite, quiet as fog, and far more dangerous to Mara's peace than any winter storm. He doesn't know Lila is his daughter. He only knows Mara vanished five years ago and has come back with guarded eyes, a child with a familiar stubborn chin, and a lighthouse everyone in town suddenly has an opinion about. Between June Pike's weaponized baked goods, Amos Reed's grim warnings, Ruth's half-buried secrets, and Graham Voss's polished offer to "save" Bellweather Light by taking control of it, Harborlight Cove closes around Mara like weather.
As fog rolls over the harbor and the old lighthouse groans under another season of neglect, Mara must decide whether protecting Lila means running again-or trusting the one man whose steady hands could help save everything she is terrified to lose. Because in Harborlight Cove, secrets don't stay hidden. They wash ashore with the tide.
