Secrets at Selwyn Castle by Anne Rollins

Every family has its secrets.

Richard Selwyn has a simple plan: throw a holiday house party to help his younger brother find a wife. Richard, having no desire to disturb his comfortable bachelor life, isn’t looking for his own match. But he didn’t expect a castle full of secrets, a jewel thief, and a kiss under the mistletoe that might very well change the course of his life.
Ivy Burnley was raised in luxury by her noble uncle and aunt, but her own parentage is so scandalous that she believes herself unfit to marry a gentleman. She arrives at Selwyn Castle intending only to help chaperone her debutante cousin during the house party. As Christmas draws nearer, winter walks, evening waltzes, and a handsome earl challenge Ivy’s resolution to stay single.
