Scion of Scales - The Ironfire Legacy, #2

After years of rebel spywork, Nula Thredsing is ready to claim her legacy. If that legacy doesn't kill her first. As the Scepter of Commerce's new liaison to dragons, she's one step away from the old family seat on the city council. Then her first meeting with dragon diplomat Tiers Sunscaler is ambushed by enemy dragons-one of them Tiers's former tactical partner. At the same time, Nula and Tiers discover a startling connection: an irresistible embermate bond.
While a political marriage suits Nula, consummation requires literal heart surgery that a human cannot survive. And then a cat-dragon and a unicorn show up to help, of all the ridiculous things. Nula must track down the rogue dragons, work with mysterious allies, and solve the problem of her mate bond before the escapable connection destroys her. Good thing she's used to impossible odds-and she has a dragon on her side. Buy now and enjoy a short steampunk fantasy book with espionage, cat-dragons, and a side of romance.
