Samantha, Sam, Thorpe loves books and trees—preferably ones with climbable branches. She plans to settle into quiet spinsterhood, at the ripe old age of 22, with one daunting task ahead of her--to find a fitting suitor for her sister, Celia.
Philip Dare, Earl of Ingram, on orders from the Foreign Office, is investigating a spy ring and is determined to find its leader. He has no time for emotional embroilment--until a certain young lady falls, literally, headlong in front of him and lays siege to his defenses.
