Playing With Fire — C.J. Hill

Having superpowers is overrated. It requires Tori to go to way more team practices than can comfortably fit into a normal teenager's schedule. Being a dragon slayer has other drawbacks too -- like fighting dragons and keeping one step ahead of power-hungry dragon lords, all without blowing her cover.
Tori Hampton is a presidential candidate's daughter, which means she not only has a public reputation to maintain, she also has a humorless bodyguard to ditch every time she needs to go on a mission.

And Dr. B has plenty of missions for the Slayers. When he discovers that someone is selling dragon scales on the black market, he's convinced the seller can give him the dragons' location. A surprise strike could turn the tide in the Slayers favor, but when they track down the seller, they find more than they've bargained for.Suddenly, strategies need to change, alliances shift, and Tori finds herself caught in the precarious middle. 

Jesse, the captain of the other Slayers team, is everything she wants, but then there's Dirk, the dragon lord's son -- who also happens to be her ex-boyfriend. He's determined to convince her that she should love dragons, and love him too. The fact that he and his father plan to overthrow the government? Details not worth arguing about.

Tori believes she can turn Dirk around and convince him to rejoin the Slayers, but he's just as convinced that she should leave the Slayers and become a dragon lord. Dirk can teach Tori how to control dragons, and it's a skill she desperately wants. It could make all of the difference in a battle. It could save her friends' lives. When Dirk offers to let her ride a dragon, she knows that meeting him is like playing with fire.

Praise for Slayers: "More than a worthy equal of the works of Rick Riordan or Christopher Paolini."--Booklist
