It's winter in Wattle Glen, a sleepy town on the edge of Melbourne where nothing much happens-until eleven-year-old AJ Fraser learns the local council plans to demolish the town's beloved (and dangerously rusty) Monkey Bars.
AJ is clever, curious, and just impulsive enough to try stopping them.
Together with her cautious best friend Fred, her parkour-mad little brother Kingston, a quiet new kid named Luca and a science mad school friend Ruby, AJ launches a campaign to save the playground-but instead uncovers a strange clue hidden beneath it. One that doesn't just lead to another secret... it leads to a trail.
As the kids dig deeper, they begin to unravel a decades-old mystery tied to an old caretaker, a one-eyed magpie, and a girl who disappeared without a trace in the 1990s. The more they uncover, the more they realise:
this isn't just about saving a playground.
It's about telling the truth before it disappears forever.
