An extraterrestrial flower causes all kinds of sexy hijinks in a Lovecraftian horror kind of way.
The book plays heavily into the ideas and conspiracy theories behind the Voynich Manuscript, a real-life unexplained document depicting all sorts of bizarre people, plants, and astronomical phenomenon, of which you can see some of the actual designs in the background. The central MacGuffin of the plot is a white lotus with purple tendrils, which I blended into the story's erotic theme by entwining it with the silhouette of a voluptuous woman. I didn't read the whole book, but it sounds pretty bonkers.
