The Substitute Mate_My Sister Begged Me to Return the Alpha

When the annual mating ceremony arrives, vain Vanessa is marked by the Moon Goddess Crystal Ball as the destined partner of Northern Alpha Arthur. Horrified at the thought of the North, she pays a witch to use dark magic and steal her mate scent, dumping the burden onto her abused sister Aria and forcing Aria to take her place. Everyone expects Aria to perish in the frozen North, but once she arrives, she finds a land far richer than anyone imagined.
