After a bad break-up, she set a goal over a defined period of time to find a partner; and for 52 weeks after that, squeezed in dates at coffee shops, wine bars, restaurants and a few golf courses.

A funny thing happened on Drummond’s road to meeting Mr. Right: she realized she was learning valuable lessons about herself, and gaining self-confidence in the process. Urged on by friends, who thought she had some valuable insights, and great stories to share, Drummond put pen to paper.
