The story
She gave up the Shadow Circle for a man who dropped her.
Isabella walked away from leading a legendary order to be with her mate, and worked as a herbalist to keep them both. The day he makes Alpha's General he breaks their mate bond and replaces her with a scheming Commander's daughter. What he does not plan for is the Alpha turning up in person to say out loud what Isabella is, which is the lost wolf princess and the next Alpha Queen.
