Edge of Darkness (The Men of T-FLAC: The Edge Brothers, Book 10)

An anti-terrorism agent with a warrior's body and a magnetic smile, Duncan Edge is working for T-FLAC's special paranormal unit on a mission to halt a lethal terrorist cell. Along the way, Duncan crosses paths with Serena Campbell, a woman of dazzling wizardry and astonishing beauty who Duncan suspects is being unwittingly used by terrorists for a vast murderous undertaking. But Serena will marshal every ounce of her energy, charms, and smarts to steer clear of Duncan, whose flirty yet disastrous childhood antics left her with a long-standing grudge.

Now Duncan and Serena, charged with an ever-growing burning desire, need to set aside their past and prejudices. In their paranormal world, a dangerous force gathers strength, and time is running out for two people who must enter the darkness together and hope there's light on the other side.
