Max, 'Inky,' and Luke are the youngest members of a secret underwater society dedicated to protecting the books and artifacts of their home from evil invaders. They call themselves the S.Q.U.I.D. Squad, and they never turn down a dangerous adventure. When Pillagers establish an outpost not far from the Book Guardian's hidden ravine headquarters, it's time for the S.Q.U.I.D Squad to swim into action.
