Our Gang, with bonus story, Under Martial Law is Max Campbell's second book with Forty South Publishing. 

In 1950s Australia, boy heaven was a clubhouse for your gang, even if it meant having to accept a girl member into the group. But when the gang finds clues leading to real-life sunken treasure, and some baddies arrive in search of that treasure, both the girl and the clubhouse prove indispensable.

Under Martial Law: In the late 1960s eight school children are forced to defend their town from a raging bushfire after they find themselves left behind in an abandoned forestry settlement.
