"The Secret of the Book" is another hair-raising voyage in the ongoing "Pahappahooey Island" adventure series. With The Book found and the ill wind calmed, Pahappahooey was saved from danger. It seemed that Ali and the gang had completed their task. That was until they learned of The Great Commission. Summoned by the Elders of Pahappahooey, the crew of the Tootie Marie discovers that The Book contains a secret message. The Elders believe the message may hold a special command that teaches them what to do with The Book. Chosen by the Elders themselves, Ali, Hobbs, hacksaw, Fernando and Millard set out on a new mission: to find the secret message of The Book and deliver this wisdom to the Elders. But little do they know that the evil snake Ichabone Slink and weasily henchman Flinch are scheming to defeat their plans. This pair of dastardly villains will stop at nothing to keep the young explorers from discovering The Book’s message.
