Brighter than the sun - Maya Banks

As the last unattached member of the Kelly clan, Joe is more than ready to risk life and limb on any mission he's assigned to, but when it comes to love, he'll keep his distance. He's content to watch his brothers become thoroughly domesticated. Zoe's had nothing but heartbreak in her life, and she s determined to start over with a completely new identity. But it's the gorgeous smile and tender words of Joe Kelly that begin to weaken her resolve to never risk her heart again. And now Joe will have to put everything on the line.
