And a rugged coastline hiding a sinister secret... When Frank and Joe Hardy set out to help a friend in trouble, they never expect to be swept into a thrilling hunt for a missing man-and a string of mysterious events tied to the desolate Honeycomb Caves. Strange figures lurk near the cliffs, unmarked cars speed through the night, and a hidden wireless tower pulses with secrets no one wants uncovered. Guided by sharp instincts and relentless curiosity, the Hardy boys follow a trail from their quiet hometown of Bayport to the windswept shores of Rockaway, where danger hides behind every crashing wave. With quick wits, steady nerves, and a few daring moves, they must solve a puzzle that stretches far deeper than the caves themselves. Timeless and packed with classic suspense, this original Hardy Boys adventure delivers twists, thrills, and edge-of-your-seat excitement.\u003cbr\u003e","brand":"Start Publishing Pd","offers":[{"title":"Default Title","offer_id":51779043852562,"sku":"9798880925575","price":7.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/4771\/8930\/files\/img_d87909e4-0dbc-403e-a91b-2819b074af18.jpg?v=1765365815","url":"https:\/\/surprise-castle.myshopify.com\/products\/the-secret-of-the-caves-the-hardy-boys-book-7-9798880925575","provider":"Surprise Castle","version":"1.0","type":"link"}
