Calvin and his mom's boyfriend, Ledward, are good friends. When Ledward wins plane tickets, he invites Calvin to fly to Hawaii, the Big Island, for a day, and go deep-sea fishing. Wow! Calvin's never been on a plane, or any boat but his skiff. What a day—Calvin catches his first big fish, an ono. But that's nothing compared to what happens when Ledward hooks a huge and very angry marlin that charges the boat! Fishing with Ledward opens Calvin's eyes to adventure and to important ideas about respecting nature.
