Closer to the Heart by Mercedes Lackey is a better read than its predecessor in the Herald Spy series. Among other things, she's not twisting around a pre-existing story.
Mags and Amily are getting married. Finally. Not that the course of a big ceremonial wedding ever runs smooth, particularly in fantasy.
A civil war in Menmellith has broken out when the new king (at the age of 10) is having issues with an uncle trying to take the throne. Problem being the Uncle is using Valdemarian weaponry, thus making sure everyone gets split apart before the big day to prevent a war with a neighboring country.
It's fast, it's fun, and if you've read any of the other Valdemar books, you already have an idea of what you're going to get.
