Diego and Martin decide to skip school. They head to a nearby beach for a day filled with sun, fun, and fishing. When clouds begin to dot the sky, the two boys worry they won’t be able to work on their tans. When purple lightning strikes, they worry about getting rained on. And when tendrils emerge from a weird boater’s mouth, they worry about their lives. This series of Hi-Lo books is sure to wrap its tentacles around any reluctant reader and refuse to let go until the final page. Each book includes discussion and writing questions, a glossary, and educational back matter.
