Autumn Frost is a thestral, and has been a loyal member of the Lunar Guard for several years. After an accident forced her into early retirement, she finds herself somewhat at a loss for what to do with herself.

Then she runs into Reed. Reed is shy, reticent, and quite possibly the biggest nerd she has ever met in her entire life--and considering who used to be the Captain of the Royal Guard, that's saying something. Namely, he's everything she isn't. Still, she finds herself somewhat drawn to him, even as events start to show her that civilian life might not be quite as uninteresting as she may have thought.
