The Blackstone She-Bear by Alicia Montgomery

Amelia Walker is finally coming home to Blackstone. Few people know the real reason why she left – her heart and her bear had been broken when her mate, polar bear shifter Mason Grimes, suddenly left her after their whirlwind romance. When she finds out that Mason is back in town too, she does her best to avoid him.
Leaving Amelia was the worst mistake of Mason’s life. But, Blackstone is his salvation, the only way he can right the wrongs of the past and provide for his daughter, Cassie, after his ex-wife abandons her. He doesn’t have time for love, but when he finds out that he’s the reason Amelia is broken, he vows to make it right.
Amelia doesn’t want to risk getting her heart broken all over again and she knows that Mason has other priorities. But, she can’t resist the pull of the mating call, but she knows she must stay away, for everyone’s sake.
Will the pain of the past keep them apart or is the pull of fated mates stronger?
