The Ivory Carver Trilogy (3 Book Series)

From Book 1:A young woman fights for survival amid the brutality of the last Ice Age
It’s 7056 BC, a time before history. On the first day that Chagak’s womanhood is acknowledged within her Aleut tribe, she unexpectedly finds herself betrothed to Seal Stalker, the most promising young hunter in the village. A bright future lies ahead of Chagak—but in one violent moment, she loses her entire way of life. Left with her infant brother, Pup, and only a birdskin parka for warmth, Chagak sets out across the icy waters on a quest for survival and revenge. Mother Earth Father Sky is the first book of the Ivory Carver Trilogy, which also includes My Sister the Moon and Brother Wind.
