Dusty Carrick lived in the small town of Skene Falls, Oregon, her entire life. And, like many of the local children, she played with "imaginary" Pixie friends in Ten Acre Woods. But the Pixies are not imaginary at all, and Ten Acre Woods is their home. Now, the woods are in danger, and if it falls, the Pixies too will die. Only Thistle Down, exiled from her tribe and trapped inside a mortal woman's body, can save her people-as long as she can convince Dusty Carrick to help her before it's too late.

Exiled from Pixie and deprived of almost all her Pixie magic, Thistle Down had made a life for herself with the help of Desdemona “Dusty” Carrick and her brother Dick. But trouble was brewing among all the Pixie tribes, fueled by Haywood Wheatland, a half-Pixie/half-Faery, who was determined to seize control of The Ten Acre Wood for the Faeries. Thistle, Dick, Dusty, and her fiancé, Police Sergeant Chase Norton, thought the threat to Skene Falls and The Ten Acre Wood had ended with Haywood’s arrest, but they were wrong. The Pixie tribes were preparing for war, and only an inexperienced Pixie named Chicory was taking a stand. And even if he could convince Thistle and her new family to help him, it might already be too late.
