Wilde Steel MC Series: Diesel

by Laura Holly

He’s the brother who never misses a thing. She’s the girl who was never supposed to walk into his clubhouse.

Diesel watches. He listens. He keeps Wilde Steel standing while louder men take the hits. Loyalty and scars are the only language he trusts, until Mara shows up looking for answers she is not owed, in a clubhouse she does not belong in.

Mara came for the truth. What she finds is a family that should have slammed the door, and a quiet man who looks at her like she is the first real thing he has been allowed to keep.

In Wilde Steel, nothing stays simple. Secrets cut. Rivalries run hotter than the engine. Old ghosts do not stay buried. When the past kicks the door in, Diesel has to decide how far he will go to protect her, and what it costs to claim her as his.

Diesel is book two in the Wilde Steel MC series. Reads as a standalone love story with an HEA and no cheating. Start with Savage for the full club war, or jump in here.
