Storm, a hard-edged biker with everything still to prove, is pushed into command of the Iron Thorns, a women's motorcycle club that lives beyond the law yet refuses the outlaw label while crossing lines to rescue a forgotten town.
She must keep the club intact, save that town, and hide what both demand of her.
A cautious, quiet woman named Shadow rides into Storm's chaos and understands her with a clarity no one else has managed.
Shadow belongs to the Steel Graces, a respectable motorcycle club that rejects Storm and the Iron Thorns, and rivalries mixed with club politics threaten to tear the Iron Thorns apart.
Storm has to discover how to lead and which convictions she will defend, and Shadow must choose whether a love with Storm is worth stepping out of hiding.
