When the local mayor is kidnapped, the people suspect other villages of taking him. But Danny's dad, Tyler, knows more. He thinks that creatures from under the sea are to blame - and he decides he's going to prove it! Join Danny and his dad on a (literally) breathtaking underwater rescue mission. Action! Adventure! Danger! This standalone book from Jonny Zucker's Toxic series is a fast-moving chapter book, filled with high-quality black and white illustrations to grab readers' attention. The Toxic series reads are ideal for reluctant and struggling readers who are enthused by short, fast-paced adventure stories. The cliff-hanger at the end of nearly every chapter certainly helps!
