is book #6 of The Inferno Club by Gaelen Foley.
==Book Description==
Notorious Lord Trevor Montgomery has fearlessly met danger head-on. Now he must confront his greatest challenge yet: marriage!
Shy, warm-hearted Miss Grace Kenwood knows she is “just” the parson’s daughter, with no chance of tempting her new neighbor, Lord Trevor Montgomery. After all, every eligible beauty for miles around is swooning over the brooding former spy. He’s the picture of sin, and though he once had the audacity to kiss her senseless, he can have no interest in someone like Grace. Yet, somehow, the seductive rogue unleashes her own inner devil…
Every lady loves a hero—but Trevor has no interest in any of them—except for the refreshingly candid Grace Kenwood. If he had a heart left, Grace might steal it. She insists he’s better than he thinks. He’s sure she’s absolutely wrong. Until danger threatens, and Trevor rediscovers how easy it is to be a hero…for the right lady.
