Seven Minutes in Heaven (Desperate Duchesses by the Numbers #3) by Eloisa James
All of Eugenia Snowe’s problems start when Edward Reeve, an arrogant bastard son of an earl, bursts into her registry office. He wants a governess and he wants her. She gives him the governess he demands, but she refuses to give herself.
No question that Eugenia enjoys crossing wits with the brilliant inventor, but she will never tarnish her reputation with an affaire, particularly with a man who doesn’t realize she’s a lady!
She holds her ground…until he kidnaps her.
Ward will stop at nothing to convince Eugenia that they’re meant to be together. He promises her heaven.
She gives him seven minutes.
