The Trouble with Earls by Anna Campbell

The wild rogue and the wallflower!
Toby Sutton, Earl of Renfrew, is a notorious libertine with no interest in marrying a wellbred young miss and making her his countess. But when he meets lovely Lady Viola Frain, irresistible desire creates an explosive mix with his native recklessness. Within a matter of days, he and Viola are joined in a hurried marriage of convenience, patched together to scotch an almighty scandal.

Marry in haste, repent at leisure?
With two spectacular older sisters, shy Viola Frain is used to being the overlooked member of the family. When handsome Lord Renfrew literally falls at her feet, Viola finally meets a man who thinks she’s special. But before the fragile bloom of attraction can flower, she finds herself wed to Renfrew and whisked away to brooding Brazey Castle, where shadows of old tragedy threaten her frail hope of happiness.

The trouble with earls…
Society watches avidly, forecasting disaster for an alliance between two people so mismatched. Can passion unite the rake and the recluse? Or is the truth just as Viola fears? That the trouble with earls is that they’re bound to break your heart.
