There's lots of fun to be had up on the beach pier, but it's down underneath where the true-and totally free-magic happens There's lots of fun to be had up on the pier-the Ferris wheel, the rollercoaster, Skee-Ball and Whac-A-Mole, cotton candy, copper coins, the carousel. But it's down under the pier, at low tide, where the real magic can be found. The best part? It's free. Nell Beckerman's poetic text and deep love of the intertidal zone, and Rachell Sumpter's dreamy, endless summer art make this the perfect beach book.
