The Brooding Bachelor (The Kerrs of Kelso #1)
Jacinta Carey

Knowing no one in London, she tried to make the acquaintance of one of their next-door neighbors, dubbed the brooding bachelor, Lord Hugh Lyon, Viscount Ferndown. He's so appallingly rude to Gwen and her youngest sister Igraine, they swear they'll have nothing more to do with him.
They may be fresh from the country, but Gwen knows a gentleman when she sees one. Hugh is mortified by the assumptions he makes as to why the two lovely young women have come for a visit, and instantly regrets his bad manners. Clawing his way into Gwen's good books becomes an obsession.
He's helped along by his glamorously rakish friend Mick Devane, the Earl of Antrim, who lives in the house on the other side of the Kerrs. Together, the two men become part of the charming Kerr family circle, and soon set their sights on their lady loves.
But Gwen's grim family troubles prevent her from ever considering a future with Hugh. And far from being an ally in Hugh's troubles, Mick manages to make things even worse. A ghost from Hugh's own past threatens any chance of him finding happiness. Can Hugh convince Gwen he's the only man for her, before it's too late?
