Wounded and bitter, Jagger sought escape in the solitude of the jungle, driven by a need to disappear forever... until a mysterious shifter who calls to his soul and feeds a yearning long forgotten, pulls him from his dark path. A courageous warrior, Skye's passion is equal to Jagger's own—but can she trust a man on the edge? A man whose secrets are as devastating as her own?
