Omega lion shifter Nathan needs to adjust to being in a wolf pack. Marcus, a beta wolf and love of his life, is taking to the new pack well, and their other mate, Zane, has just become the alpha of the entire pack! Everyone is waiting for Nathan to screw up, to distract his mate and to be everything they need in order to hate him. Nathan will be the best, most supportive mate he can be, even if it means his awesome, strong, handsome alpha can't spend as much time with him or Marcus anymore. Supporting his mate becomes harder than Nathan expects it to when he has to smile at the lion shifter who wants to destroy everything he loves. Nathan doesn't know if he can keep his mouth shut when all he wants to do is defend his mate, even if defending his mate from the lions means throwing him to them.
