In a Nutshell: clumsy, black-sheep princess turns out to be Dragon-slaying, world-saving princess

Aerin may be the only child of the king of Damar, but it hasn't won her a big fan following so far. For years, people in and out of the royal court have whispered stories of how her witch mother used magic to ensnare the king in marriage and get an heir on the throne, and how she died of disappointment when her child was born a girl.

Aerin longs to do something of use for her father and the kingdom, so with the help of her cousin, Tor, she secretly learns to use a sword, and she becomes Aerin Dragon-Killer. Dark powers are stirring in the north, and though smaller than their legendary counterparts, small dragons are becoming a dangerous nuisance in the villages. But rumors exist in her father's books that one of the great dragons may still be alive, dormant and waiting to rise again and cause fiery mayhem. And there is still another problem to consider: the common source of the dragons, the rebellious spirit in the northern lords, and more ominous signs of dark times to come. She may have been belittled by people all her life, but Aerin's country needs her now for the gifts she never imagined she had.

A classic high fantasy; dragon-slaying and magic destiny-discovering adventure at its best. I'm glad I finally got around to reading it. And if you want more there's also The Blue Sword, written two years before this one but set much later in the history of Damar.
