Lord of Storms - Night Lords, #3

Advertising executive by day and novelist by night Gray Stewart has retreated to the country for a much-needed vacation.  She's at the top of a mountain when lightning threatens to fry her to a crisp.  She finds shelter with a mysterious man who goes only by Rowan. Rowan is the Lord of Storms, a super-human being who has power to minimize the damage of dangerous storms.  He works in secret, and his female visitor is a threat to that secrecy.  She's also a threat to his equilibrium because as long as she's around, his thoughts keep straying to sex.
and love.
