Rush. Dragons For Hire, #3

Xedron broke a rule and now it's cost him. He's the prisoner of a madman scientist who wants his dragon blood for nefarious reasons. Sadly, none of Xedron's brothers know where he is. Cody's just recently met the man who fathered her. Fletcher's finally a part of her life. It's especially bittersweet now that her mother's dying of cancer. Cody's not normally a nosy sort, so she can't explain why she's gone poking around in Fletcher's basement.
What she didn't expect to find is a hot guy in a cage. Fletcher tells her he's a serial killer but something doesn't seem quite right about her recently-found father's explanation. Who is this gorgeous hunk? Why is he her father's captive?
