The Trouble with True Love

"For Clara Deverill, standing in for the real Lady Truelove means dispensing advice on problems she herself has never managed to overcome. There's nothing for it but to retreat to a tearoom and hope inspiration strikes between scones. It doesn't--until Clara overhears a rake waxing eloquent on the art of 'honorable' jilting. The cad may look like an Adonis, but he's about to find himself on the wrong side of Lady Truelove"--Amazon.com.
