Day of the Dragon: Two full books for the price of one by Katie MacAlister
Helen Larson used to be one of the most feared dragon hunters in the world--until she lost her powers. She can't remember exactly what happened, but the timing really couldn't have been worse because a demon is on the loose wreaking havoc. To get back into fighting form, she'll have to pass a series of tests. And only one man can help her...
Morgan Boas has been training for adventure his whole life. He's got the muscles, the movie-star looks, the swashbuckling swagger, and one helluva big sword. He'll be able to whip Helen into shape to pass her trials, no problem. He's happy to do anything that will give him a chance to spend more time with the woman he's been crushing on for years. But when the High Council thinks maybe he'd make the better dragon hunter after all, he'll have to convince them that only with Helen at his side as a full dragon hunter can he be expected to protect the mortal world.
