Heart of Fire - Dragon-mage, #1

A SLAVE DETERMINED TO RIDE A DRAGON. A CHILD CHOSEN TO RIDE THE OBSIDIAN GUARDIAN. Camilla has always been told that humans are inferior. They cannot use magic. If they bond to dragons, they will doom the creatures to extinction. She has never believed a word of it. She has always known that she can use magic, and she suspects it is the elves who harm the dragons by keeping them to themselves. Now, she is presented with the opportunity of a lifetime: a dragon's clutch is hatching and while she will earn the wrath of her captors if she is caught, she has the chance to see a dragon hatch and perhaps even to Recognize. Kario's people have feared dragons since time immemorial.
When an unrealistically huge black dragon flies in while she is hunting, she is certain she will die. Instead, her life is changed when Nelexi, Obsidian Guardian of Areaer, chooses her as her final rider. Kario takes the name Flameheart, but she is soon homesick and afraid that she is insufficient to be the partner of a god.
