Joe didn't mean to release a scary dragon from a magic book. He just happened to crash into the library shelves while skateboarding and wanted help cleaning up. Now the dragon is out for revenge, and it's up to the skateboarding yeti and a quiet librarian to save the entire school from complete destruction. As the adventure unfolds, striving readers practice decoding words featuring long vowel teams, as well as common suffixes. Every Spark Decodables book serves older readers who need practice with foundational literacy skills, combining multiple aspects of the Science of Reading to support small group instruction, independent reading, and reading practice at home.
