A grumpy dragonman and a flighty but brilliant human female lawyer end up locked together in a secret underground bunker

Hayley Beckett's sister desperately needs a shot of dragon's blood to save her life. She's a lawyer who helps dragon-shifters and refuses to buy it on the black market, nor can she join the sacrifice program because of the importance of her job. However, after helping Clan Stonefire with a recent case, she hatches a plan. In exchange for her help in creating a more centralized law and case database for the dragon-shifters, they'll give her sister the much needed treatment. What she didn't plan on was being paired with a grumpy yet sexy dragonman who sees everything she does as a nuisance.

Nathan Woodhouse is used to dealing with the alpha Protectors on Stonefire. He does his job, they leave him alone. It's perfect. Then the clan leader and head of security assign him a job to design a legal database for a human female. He'd much prefer working alone and communicating through email, but she insists on working inside the clan because it gives her access to their records. When she accidentally triggers an old mechanism that locks them in a rarely used area of the clan, he can't ignore her. And then his dragon decides he wants her.

As they tackle their project and the mishaps along the way, word gets out of what they're doing and a familiar enemy causes some trouble. Will Nathan and Hayley be able to admit their feelings and be together? Or, will Hayley have to flee Stonefire and possibly the UK for her safety?
