Angel Heart. The Ryan Chronicles, #2

I have no memory of my life beyond waking in a hospital room. They tell me my name is CJ Ryan, and I have been in a coma for a little over two years. Apparently, it's a medical miracle that I am even alive, much less awake and coherent. I have no idea what they are running on about. My stutter is hardly articulate, and it makes communicating a real bitch. But the media loves it, the story of the 'coma boy wakes!' I'm thrust into the forefront of the headlines.
The push into the spotlight shines a harsh glare on my family and brings with it a plague of horrors that drag me to the edge. With each supernatural encounter, another power is revealed, and I have no idea what the hell I am, or how to control this raging magic inside me. I need answers and I turn to my brother, but he isn't talking. No one is. Because every time I get close to glimpsing my past, my brain shuts down violently, causing me seizures.
Seizures that could kill me. When an enemy with a psychotic history reenters our lives, it will take more than just my memory to save us. I must harness my memories along with all the powers inside me to survive the upcoming onslaught.
