When three teens on a cross-country RV trip with their quirky grandparents end up in the coastal town of Stone Cove, Maine, they expect lobsters, lighthouses, and maybe some corny souvenir T-shirts. But when they stumble upon an old map and a stash of hidden Bibles, they're swept into a treasure hunt with more twists than they can navigate. There's the old sea captain's ancient note about buried jewels, a church basement with some serious secrets, and a deacon who's suspiciously tight-lipped about the whole thing. Add in a lobster fisherman who seems to be everywhere they go, a rich guy who really should've changed his internet password, and an unexpected showdown in a cemetery at midnight, and you've got all the ingredients for a mystery that's equal parts thrilling and downright hilarious. After all their sneaky spying and questionable decision-making, the teens might just need a confessional! Will they find the jewels before the bad guys do? One thing is certain: this seaside mystery is going to be the wildest stop yet on their cross-country adventure!
