Shadow Angel

I didn't think there were any more surprises, but I was wrong. My mission hasn't changed, defeat Apollyon and free the souls trapped in the Netherworld, but everything just got a lot more complicated. I have a sister, my boyfriend's a shifter controlled by my enemy, and now it's not just my life that's in danger, but my soul as well. As the ruler of the Netherworld amasses an army, my to-do list gets stranger by the day. Sneak into Shade City. Get my boyfriend wings. Find a lost realm. But even if I manage to pull all that off, one burning question remains. How do I defeat an enemy I can't kill without dying?
