Wow! This book was mentally exhausting - but completely amazing all at once! There is never a dull moment for Allison, that's for sure. She's extraordinarily loyal and strong, and still possesses a lot more of her humanity than most vampires do. But there are a few who just love to test her limits. And then there's Sarren - probably the most terrifying, sadistic, whacked-out, psycho-freakin-crazy-ass villain there is! As if Allie doesn't have enough to deal with already, add a new strain of the horrid Red Lung virus to the mix. Be prepared to be put through the ringer as you devour this book - it's painful, terrifying, beautiful, disgusting, shocking, and maddening. And I loved every second of it! I need more NOW!!
