Jones is determined to find out what caused the unexpected death of her father while they were exploring ancient ruins in the Himalayas. Along with a stack of books and coded journals, he's left her with the promise she'll travel back to England for the first time since childhood to try being the lady she's never been.

Edie and her brother are leaving soon on a journey to the Himalayas to document and collect plants for the new Kew Gardens when she befriends Miss Jones in London. She's never left England before and is delighted to learn the lady will be returning to the mountains she calls home at the same time they are planning their travels. When they meet again in Srinagar, Edie is surprised to find that, out here, the Miss Jones of the London salons is "just Jones" the explorer, clad in breeches and boots and unconcerned with the proprieties Edie has been brought up to respect.

The nonbinary explorer and the determined botanist make the long journey over the high mountain passes to Little Tibet, collecting flowers and exploring ruins on the way. Will Jones discover the root of the mysterious deaths of her parents? Will she confide in Edie and allow her to help in the quest? The trip is fraught with perils for both of them, not least those of the heart.
