The Roots of Passion by Lavinia Roseknight

An architecture office of vampires, and a nature-loving fae living in a forest, all set in the beautiful and historic town of Weimar, Germany. Enter the exciting world of the Vampires and Fae of Weimar!
He was whole, just in a different way than her. Still, they had so much in common.
A fae forestry specialist, Ashley Thompson, comes from the States to Weimar, Germany. Her task is to help the Thuringian Fae with curing a mysterious illness in the woods. How can she focus on her job, though, when she soon gets caught up in politics?
A local activist, the human Ursula Koch, proposes using part of the forest for the construction of an amusement park. As outrageous as that concept is to the fae, the Council has to respect the voices of all species. To compromise, Ashley is tasked to work with a Landscape Architect, Elias Imelhardt, on designing a park for the land instead.
However, Elias is a vampire, so the life-loving fae has to overcome her prejudice against his kind. But what is this attraction she’s feeling towards this man?
