Aisling Grey is a courier enjoying a free, work-related trip to Paris when she learns she's a Guardian. That's a keeper of the Gates of Hell, for those who don't know. She finds this out from Drake Vireo, who's scrumptiously sexy-at least in his human form. Now Drake has stolen the package Aisling was sent to deliver, and she must track him down, get the package, and try to resist the passion boiling inside her.

Aisling Grey is juggling being a demon lord, a Guardian, and a wyvern's mate, even though she's keeping her distance from said wyvern, Drake, these days. But her presence is still required at a meeting of the green dragons. Since several attempts have been made on her life, Drake is sure to get protective of her. Which might not be a bad thing when war breaks out and all hell breaks loose-literally.
