For Nim, lifeguarding is more than just a summer job. She and her friends are Rescue Sirens, mermaids sworn to an ancient vow to watch over and protect humans -- and the best way to do that in today's world is by hiding in plain sight as lifeguards. When the Rescue Sirens receive word that a special human -- unwittingly possessing the rare power to turn into a mermaid -- has made her way to Miami Beach, it's up to them to find her before she transforms on her own and she's either discovered... or lost forever.

Written by Jessica Steele-Sanders and Academy Award-nominated animation writer/director Chris Sanders ("Lilo & Stitch," "How to Train Your Dragon," "The Croods"), and featuring interior illustrations by Genevieve Tsai as well as cover art drawn by Chris Sanders and colored by Edgar Delgado, "Rescue Sirens: The Search for the Atavist" is the first book in the "Rescue Sirens" series.

This second edition includes eleven pages of full-color character artwork by Chris Sanders.
