Books like The Highest Tide

One moonlit night, thirteen-year-old Miles O'Malley sneaks out of his house and goes exploring on the tidal flats of Puget Sound. When he discovers a rare giant squid, he instantly becomes a local phenomenon shadowed by people curious as to whether this speed-reading, Rachel Carson obsessed teenager is just an observant boy or an unlikely prophet. But Miles is really just a kid on the verge of growing up, infatuated with the girl next door, worried that his bickering parents will divorce, and fearful that everything, even the bay he loves, is shifting away from him. As the sea continues to offer up discoveries from its mysterious depths, Miles struggles to deal with the difficulties that attend the equally mysterious process of growing up.
