Kestrel's land is scarred in ways its inhabitants cannot begin to understand, built on long-poisoned earth and menaced by twisted plants and animals. Farmers, hunters, and magic-users fight a long battle to create safe havens and reclaim lost ground, but their casualties mount over generations. Kestrel knows little and cares less about the patterns that shape her world. She's a shapechanger and healer who has spent the handful of years since reaching womanhood cleansing the wildlife of her blighted land with medicine and magic. Sure of her place and confident in her skills, she takes care of her own and doesn't poke at things that don't concern her. But when she returns from a routine journey with her brother to find her home ransacked and empty, Kestrel must gather her remaining family and search for new allies before old magic and older hatred rob her kin of their freedom, their lives, and possibly their souls.
