For fans of The Magic School Bus and Magic Tree House, new friendships, mysterious forces, and an island adventure awaits in The Bridge to Sharktooth Island as you delve into the mechanics of bridge-building fun! One second cautious Daniel and his brave cousin Joy are playing in the snow, and the next second they’re suddenly stranded on a mysterious island surrounded by sharks.
