The 'Outer Banks' novel is actually based on the Netflix series, and as far as I know, there isn’t an official novel adaptation. But if you’re looking for something with similar vibes, you might enjoy books like 'We Were Liars' by E. Lockhart or 'The Summer I Turned Pretty' by Jenny Han—both have that mix of teen drama, romance, and coastal settings. For free reads, check out platforms like Wattpad or Archive of Our Own where fans sometimes write spin-offs or inspired stories. Libraries also often have free e-book loans through apps like Libby.
Just a heads-up: while some sites claim to offer free books, they might not be legal. Always support authors when possible! The 'Outer Banks' show itself is packed with enough twists and treasure hunts to feel like a novel anyway—maybe rewatching it could scratch the itch while you hunt for the perfect read.
