Dark Rider

Ehhhh...spunky heroine, but sometimes to the point of deliberate obtuseness regarding her willingness to investigate her own motives, despite lots of narrated rumination? Hero hellbent on revenge in a fairly simplistic manner, then a 180 near the end? A little too much reliance on the idea of “animal instincts” to characterize their attraction to each other? Plus an annoying pattern in which they each basically orgasmed very quickly and at the same time. There were three good supporting characters here, and the dialogue often zipped along, but I didn't find it particularly compelling overall.
