"Tess is a Switcher, able to change shape at will—and it’s time for her to choose her final form Tess is a Switcher, and can change into any creature, including ones thought to be imaginary. Within days, she will turn fifteen and lose her power, remaining locked into a single shape. But what shape should she choose? As she tries to decide, Tess travels to her Uncle Maurice’s farm in County Clare. She’s distracted from her weighty decision by the feeling that there’s something strange about the woods near her uncle’s farm. Why is Uncle Maurice so eager to sell that land? And what does the secret in the wood have to do with Tess’s choice? Tess’s journey will take her to places she never could have imagined, as she approaches once and for all her final Switch."
