Wulff’s cogs are in a jam because of Ursy, his best friend’s little sister. Only she’s not so young and bratty anymore. And she’s got a nice set of gears.

However, Wulff has no intentions of stealing her upgrades. Nor is he interested in bedding her, even if she makes his parts steam. He really should stay away, and yet he enlists her aid in tracking down a treasure.

A mission that’s going fine until the kiss.

Now, he can’t help seeing her in a new light, but Ursy isn’t interested in a relationship, even as she invites him to her bed.

Problem is he wants more than just a temporary meshing of their parts. He won’t settle for anything less than her heart.
