Snowbound Fate: A Wolves of Riverton Novella by Haven Gwynn

Jeb Donaldson made some very bad life choices, and now he's shunned by most of the people of the Redwood pack. He's used to it though, having spent his entire life on the fringes of shifter society - too big, too dumb, too unlovable. One winter night, he stumbles across an injured, unconscious human woman in the snow and suddenly his entire life is turned upside-down. Isla Wallace escaped a werewolf kidnapper, only to be stuck in a remote cabin in a blizzard with a strange, enormous man. Both human and wolf struggle with trust, with their own insecurities, and with a growing desire that neither expected.
