Sam is not looking forward to the upcoming summer vacation until he meets Simon, the new boy at school. Together they form a club, The Bats, and work together to create secret signals, rituals and everything else a proper secret society requires. They also set up a system of booby traps to keep the neighbourhood bully Ted and his gang, The Gorillas, from getting into the new clubhouse. But Sam and Simon catch more than they bargained for in their trap and become the city's newest heroes. This Level 4 First Flight Chapter Book portrays two young boys that newly-confident readers will be able to identify with as they follow Sam and Simon's summer plans into an exciting adventure.
