A dinosaur + dinosaur romance novel would be something awesome. Tales of meeting over a leafy tree, the thrill of the hunt (for food), the joy of...sitting on eggs. I'm getting steamy just thinking about it.
Sadly - or not, depending on your tastes - these dinosaur romance novels are not about that. They're about human women (or sometimes men!) falling in love with dinosaurs. Or sometimes Gryphons. Or orcs.
They're the work of Christie Sims, who has written a ton of them. Her bio is amazing:
Hi! I'm just a plain old, everyday Midwestern girl that lives a normal life. However, while my outward tastes are relatively simple, my inner thoughts are filled with lusty thoughts of big, strong, powerful monsters having their way with beautiful maidens.
Her Amazon page is here. Prepare for amazing cover art.
