Crimson by Jessie Cooke

Eric “Crimson” Adair came from Scotland to America with one thing on his mind, to find his little brother Lucas and take him home.
Amelia Sanders is looking to escape her overbearing brother.
A mysterious woman named Mia will bring the two together and while Crimson turns to the Southside Skulls for help finding his brother, Amelia will struggle to escape from the ranch, and from Mia.
The only problem she’s facing: How does a person escape a part of herself?

Dax Marshall is smart, savvy, and sometimes ruthless.
His leadership of the Southside Skulls has taken them to places that even his father, the legendary Doc Marshall, never thought they could go.
But when he agrees to help Crimson track down Lucas he inadvertently pulls the club into a dangerous web that involves a hit man, a Mexican drug lord, and the FBI.
Dax and the Skulls are prepared to fight to defend their club and their territory, as always, but what Dax never bargained for was the kidnapping of his sweet little girl, and the turmoil that follows.

From Mexico to Boston, this action-packed story will explore mental illness, family loyalty, and the tightrope that is often walked between the right and wrong sides of the law.
As usual, the Southside Skulls, led by the one and only Dax Marshall, are ready to take you on a wild ride.
