I'm going to start with Alaidia ("Peter's Angel"), since that is the work I most frequently discuss here. Let's see...
***
The coronation of Alaidia's crown prince is not a happy time for Peter, the heir of Reval, a large Alaidian fief. When the childless Alaidian king names his nephew Mark as his heir and gives him charge of Reval, Peter bitterly hopes that the new prince won't meddle in Revalian affairs. Mere weeks after the coronation, however, precious oil is discovered in Reval - and Mark tries to bargain for the land. When Reval tactfully refuses, Mark is incited to seize the land by force, waging war on the coasts. Peter urges retaliation, but before he can make it to the front lines, he is ambushed and kidnapped.
Unbeknownst to both governments, the war forces Nathan, the orphaned son of Alaidia's rightful king and queen, onto the streets. Stumbling through the woods in search of shelter, Nathan witnesses Peter's kidnapping and trails the prince until he has a chance to free him. But before Peter can even offer a word of thanks, Nathan vanishes, leaving Peter with only a memory of Nathan's scarred wrist.
Going on that memory, Peter scrounges the countryside until he finds "his angel." Indebted to repay his rescuer, Peter makes a name out of Nathan, bringing him to the attention of Mark. When Mark makes the connection and reveals Nathan's true identity, Peter throws himself into a war, sworn to not only save his angel's life but restore him to his rightful throne.

That could use some work... I will try writing summaries for some of my other works, and I'll probably rewrite this one later.

Looking forward to seeing some others!
