Who's My Triplet's Alpha Daddy?

Thalia has spent her life as the shame of the pack and her family, but everything changes during her first heat. Locked in her room by her parents, she escapes-only to spend one impossible and passionate night with both Alpha brothers that shatters every wall between them.
Eight years later, Thalia has transformed from a broken teenager to a steel-spined lawyer, raising three children alone. But when her firm is acquired by Fenris Law Group, she's forced back to Seattle-back to working under the two Alpha heirs who never stopped searching for her.
