Name Seeker: The Grave of Crowns

Swift Wings has lived herself an outsider among her caribou herd. She wants nothing more than to forget her mother, who abandoned her
herd of the Highlands to be with Swift Wings's father, and then abandoned his herd of the Lowlands when he died to return to her own. She wants everyone else to forget her mother too - and most of all, she wants to earn her third name like her brother Broad Wings Flashing, and mighty caribou warrior, and follow in his hoofprints as a protector of their herd.
But the day Swift is denied her third name, the legendary White Stag appears, a white caribou said to bring doom on his hooves. He asks for brave warriors to join him in an impossible quest: to seek the Great Elk and find answers that will avert the coming doom and save both herds.
Eager to earn her third name and prove herself, Swift Wings is the first to volunteer. Joined by her brother and the lame-legged healer apprentice Little Birds Dancing, the four set out to find their god and bring home answers.
Treachery, ice, and wolves await them.
