Forest Moon Rising. Tess Noncoire Adventures, #4

Tess Noncoiré, best selling fantasy author, wielder of the Celestial Blade, and companion of a pandimensional imp, Scrap, has pulled up stakes in New England to settle in Portland, Oregon, far from the man who broke her heart. Here, she can stalk the trails of Forest Park in search of the Nörglein, a dark elf bent on repopulating his species by raping joggers. Dr. Sean Connolly, a handsome, young, ER doctor, who has treated the assaulted women, eagerly joins Tess in her quest to end the Nörglein's evil.
She's vulnerable to his attraction, but he can never be the renowned Guilford van der Hoyden Smyth Ph. D., Gollum, her former lover. Before the dark lord can be caught, two of his daughters escape his abuse to seek refuge with Tess. Their stories convince an entire posse of Tess's friends, including Lady Lucia, a vampire crime boss from Las Vegas, that the reign of terror must be stopped by any means.
Inevitably, both Tess's former lovers, Gollum and Donovan, join the search. Now, Tess must protect the innocent girls while fighting her own heart, jealous lovers, and an evil elf bent on destruction.
