Arrow's Flight

You know The Forbidden Tower, by Marion Zimmer Bradley? Ok. So, pretend that's what we're talking about. Got it? Now take out about half of the main characters (Ellie and either Damon or Andrew). Take out the miscarriage, the betrayal, the wedding, and the murder for good measure. So what are you left with? Two people, holed up for the winter, obsessing about the woman's psychic gifts and how she can't make them do what she wants.
Yeah. Sounds fun, right? That's pretty muich Mercedes Lackey's Arrow's Flight, in a nutshell. Except that in Bradley, there were certain world-changing implications to Callista getting her head in the game (as it were). Here, not so much.
