Chosen as one of hundreds to journey to the top of the glacier in their village, Sabira will embark on a dangerous pilgrimage that will guarantee her a life of importance, but only if she can survive. On Choosing Day, children of Adranna who reach the age of fourteen are finally eligible to undergo the tests to determine if they are worthy of bonding a Frostsliver. Only one in a hundred are destined to succeed. If chosen, they will have to climb to the top of the glacier and cut a piece off for themselves, so that they may be granted the powers they've always dreamed of. When Sabira is chosen, an entire world of possibilities opens up to her. But in order to see it through, she'll have to embark on a dangerous pilgrimage to the top of the glacier. When a huge avalanche traps her on the glacier and destroys the pass, she must face up to the merciless mountain -- but there are dark and fiery secrets hiding in its depths.
