Miss Sophie Kendall is passionate about plants, their properties, and the Debutante Underground. One thing she doesn't love is running into a sleep deprived earl as she's sneaking into an abandoned building for her next meeting. With her knowledge of plants, Sophie knows she can help this surly, enigmatic man but he has a proposition.

Henry Reese, the Earl of Warshire, wants to be free from his wartime nightmares. So when Sophie brews him a special tea, he thinks he's found a cure. But it soon becomes clear it's not the tea that's helped him sleep. Reese has an offer: she can use his building for her meetings, and the garden, in exchange for one week at his home to help him sleep. The rules are simple: No touching. No closeness. Only one way to fall in love.
