The Divided Realms: Captured (The Divided Realms, 1)

Fifteen-year-old Willow Kingswell has been listening to her Nana's tales of faeries and enchanted kingdoms for as long as she can remember. But when she is magically transported to the realm of Mistolear, she is stunned to learn that the stories were true, and that she is actually a princess. Suddenly, Willow has to fit into a royal family she didn't know she had, deal with customs she doesn't understand and sort out her feelings for Brand, the handsome knight who has sworn to protect her.
On top of everything, she may also be the key to saving Mistolear from a terrifying spell. The nefarious faerie prince Nezeral has pitted two kingdoms against each other in a life-or-death chess match, in which people are the game pieces. As a pawn, Willow now glows with the light of the game and must find the courage and cleverness to battle Nezeral before her loved ones fall. Could a meager pawn really be the most powerful piece on the board? Captured is the first book in the thrilling Divided Realms series.
