Revision Donkey: Horsey to King's Prawn Four

Killer-Kate and Luke Lackland: First pass on the horsey stuff, of which I know very little. I went through looking for major errors/ideas with the aid of Judith Tarr's extremely helpful Writing Horses, and her Horseblogging posts at Book View Cafe, both of which I can highly recommend.

For non-horsey folk: what horse-related stuff throws you out of the story, or draws you in?

In other news, my home Internet was on the blink again this morning, so communications may or may not get irregular presently.
