Rain maintains the science projects that allow the Fae to walk on the iron-cored earth, but she can't figure out what her Fae boss wants. She's tried blonde, brunette, C-cup and D, slutty heels and flats. Nothing works. But with the Fae mating season coming up, she's pulling out all the stops. Titan has explored the galaxy - and found the one woman he can never have. Rain is perfection, but he won't risk losing her in a mating ritual that could kill her.
