Vault of Bones. Land of Szornyek, #4

In a world of monsters, the hardest choice is who to trust. Winter closes in as Askari and her companions march north under orders from the Lamplighters Society. Their mission is clear: find the Weatherman, the one man who might know how to locate the portals unleashing monsters into the world. With Minda leading, and Harcos, Shujaa, and Rudi at her side, Askari hopes success will finally bring them closer to ending the threat.
But the Weatherman has vanished. Their only lead is Moose, a prickly trader whose knowledge may guide them deeper into the snowy wilderness. Yet danger waits in every shadow-monsters stalking them in the snow, boneshredders guarding the Vault, and creatures like Arrow, a monstrous bear whose loyalty is as uncertain as his claws are sharp. Every step deeper into the frozen wilds tests her resolve, her companions, and her faith in Polly's guidance.
But when trust becomes as perilous as the monsters in the snow, Askari must decide which risks are worth taking-and which will cost them all. This book contains fantasy violence.?This is the second edition.
