From Amazon.co.uk:
Although she was born into the ancien regime, Juneclaire Beaumont now lives as a poor relation - until a crisis sends her packing. But the road to London is not easy - and she must take shelter in a stable with a handsome, scowling stranger, also in a predicament. He could take advantage of the situation - but behaves as a gentleman. The ton, however, would never believe the rakish Earl of St. Cloud could act the nobleman for a moment, let alone a whole night. But he will prove them wrong: after Juneclaire slips out of town, the earl will spend the twelve days of Christmas on a neck-or-nothing ride to find her...
