Born with two larger, stronger brothers, Cordelia learns very early how to stand up for herself. Her parents are proud of her courage and tenacity, but they have no idea how valuable those characteristics will be when their peaceful valley home is threatened.
Her father, Corzell has a premonition that something evil is coming to the valley. But the five valley clans are still caught off-guard when the Krat clan, led by Captain Kratt invade the valley and start to banish other magpie clans to take over the clan lands.
During the fight to repel the invaders, many lives are lost. After receiving a head injury and falling into the back of a ute, Cordelia is whisked away to a property hundreds of kilometres from the valley. With no memory of her former life, she must re-discover who she is and where she is from, before finding her way back to the valley to seek revenge on Kratt.
When she returns, what greets her is not one problem but two. In the final fight, assistance comes from an unlikely source.
