Colt is introduced in ‘His Innocent Mate’ Unforgiven Country #1, when he refused to accept Wyatt as his alpha.
As children, their respective fathers were best friends, Wyatt’s father the Alpha of the pack, Colt’s next in succession. They were both training to assume control, to rule the pack together, as a team. Right before Wyatt’s father passed, he elevated Wyatt to Alpha, totally disregarding Colt’s father’s rightful place. Then he passed away, and Wyatt became Alpha. There was an unexpected pull of power, placing a strain strain between them, driving a wedge that stripped friends apart, making them enemies. And then, when Colt’s father passed away things worsened. There was no further discussion of togetherness, the bitterness that had festered in both of us too much to smooth over, too deep to even repair.
Jasinda is a wolf-shifting runaway escaping from her family, and her pack. Arriving in the mountain town, Unforgiven Country. She left, escaped her duties, turned her back on her pack, her father, and the man she is betrothed to, treated as a pawn, a mere commodity.
There is a confrontation between her fated mate (Cole) and the one she’s promised to (Stark), when her father finally realises his actions are hurting her. Wyatt and the pack all support Cole as he defends his mate Jasinda. They ultimately reconcile and live happily ever after.
