 Princess Kimri has been betrothed to a king from a neighboring kingdom, a man she's never met, in exchange for arms to fight a war. She's not too thrilled with the arrangement until she reaches Helsmont, where she's promised a year to decide whether she truly wants to marry Tathan, the king. It doesn't take her a year to fall in love with Tathan, the kingdom, and the people, but when her family is directly affected by the war, she must make a decision, whether or not she can rely on Tathan's help. 
 This was a nice little story; it wasn't too long or deep, but it was enjoyable. I did wonder, by about halfway through, where the conflict was--Kimri's needing to decide whether she really wanted to marry Tathan was hardly conflicting, especially considering how nice he is. In fact, everyone in the story (at least until the last bit) is so nice that there really wasn't room for conflict until the war got personal. Because the story's so short, the conflict was resolved really fast and really easily, but not without satisfaction. 
 There are dragons, and really interesting versions of dragons, though they, also, don't show up until the endish of the story. I liked that we were kept (mostly; I figured out the Big Secret about the dragons about halfway through) guessing about the realities of dragons until they actually showed up. 
 Heart of the Dragon's Realm will be available on October 29.
