Taming a Gentleman Spy (The Spies of Mayfair #2)
Maggi Andersen

Lady Sibella Winborne has refused several offers of marriage since she first set eyes on the handsome Earl of Strathairn. Sibella’s many siblings always rush to her aid to discourage an ardent suitor, but not this time. Her elder brother, Chaloner, Marquess of Brandreth, has approved Lord Coombe’s suit. Sibella yearns to set up her own household. She is known to be the sensible member of the family, but she doesn’t feel at all sensible about Lord Strathairn. If only she could forget that kiss.
