Summerkin (Winterling Book 2)

Summerkin, the second book in award-winning author Sarah Prineas’s fantasy-adventure series that begins with Winterling, follows Fer, a young healer and warrior who’s fought to become the Lady of the Summerlands and now faces the task of ruling over a magical people in an enchanted realm.
 
Although Fer defeated the Mor, the evil, false Lady who terrorized the Summerlands, there are still those who do not trust her. To prove herself, Fer, aided by her deep connection to the natural world and her healing arts, enters a challenging contest. If Fer fails, she will lose her land and the realm will be closed to her forever.
 
Sarah Prineas combines a brave and resourceful young heroine with a richly detailed fantasy world and beloved folklore into a story that will delight middle-grade fans of Diana Wynne Jones, Ingrid Law, and Rick Riordan.
