If Angels Burn by Lynn Viehl is the first novel of the Darkyn. Dr. Alexander Keller is Chicago's most brilliant and fastest reconstructive surgeon. Michael Cyprien is New Orlean's most reclusive millionaire and in desperate need of Dr. Keller's skill. Michael is one of the Darkyn, or a vampire to humans. Alex is the fastest surgeon around and Michael needs her to preform his surgery as he heals as soon as he is cut, unless it is copper. Alex repeatedly turns down money to come to New Orleans to perform the surgery, so Cyprien has her kidnapped and brought to him to perform the surgery. Once the surgery is complete, Michael "feeds" from Alex and ends up taking too much blood and Alex starts to turn to Darkyn as well.
Alex is returned to Chicago with really no memory of her time in New Orleans. Michael eventually must go to Chicago to check on Alex and finds her only to learn that she has found a way to slow down the process of turning to full Darkyn. He makes a deal with Alex to return to New Orleans to help other members of the Darkyn with her surgery skills.
The Darkyn have enemies called the Brethren, who are priest that are trying to end the Darkyn race. Alex's brother John is a priest who the Brethren induct as one of their own. John of course has no idea that by killing members of the Darkyn, he will eventually have to kill his sister. In a battle against the Brethren, Alex must finally make the decision to either stay half human or full Darkyn. She must also decided whether or not to continue to fight her feelings for Michael.
I really enjoyed If Angels Burn and can't wait to read the next books in the Darkyn series. I found this series after many books were released, so I have many great books to look forward to reading.
