A water ride like you've never experienced before, featuring the cutest drop of water in all of precipitation—part of the Science Pals series, including Ray: How Light Works and Puff: All About Air Meet Drop. She's water! And she's seen a thing or two. Yep, even dinosaurs; she's four and a half billion years old, after all. Everywhere Drop flows--and she flows every where--she keeps things moving, making life on earth possible, and having a great time doing it. (Have you ever plummeted from a rain cloud? Or took a thousand-year nap in a glacier? Drop knows how to live right.) With delightful panache and a steady stream of funny one-liners, Drop takes readers on an adventure through the water cycle and beyond. Filled with irresistible artwork, funny asides, and a steady sprinkle of kid-enticing facts, Drop is the story about water you never knew you were thirsting for. "Splashy and original." — Kirkus "A stand out from others of its type." — SLC “An endearing, conversational introduction to the water cycle.” — PW
