Jagged Little Pieces by Bijou Hunter

Martin “Walla Walla” Carter grew up under the thumb of a repressive family. He found freedom with his friends, who eventually became the Steel Berserkers Motorcycle Club.
The fiercely loyal biker volunteers to travel to unfamiliar territory to track down the men responsible for making his people bleed. The plan is simple—use Urick Halvorson’s daughter as bait and wait for the enemy to reveal themselves. Except Walla Walla’s long harbored feelings for the girl who got away. Now, he plans to do more than seek revenge. He’s looking to win Austen’s heart.
Austen Halvorson used to be a daddy’s girl, but their relationship soured after he downplayed a violent incident by his workers. She walked away from him and her dream of catching the eye of a sexy biker.
Now her father’s problems have put her life in danger, and Austen’s only hope is the man she thought she lost forever.
