Bulletproof

Invincibility. It seems like it's perfect for some. Not for Blythe. Her family has been immortal for some time. However, it's not the same kind of immortal you would think. Anytime they get hit, nothing happens. The only way her family could die is if they get a sickness that only they can get. Blythe soon finds out that her family isn't the only one, and it's become a growing problem.

She finds out that the immortal groups have been named the Unsterblich, and that another group Uccisore has been hunting them down to keep them as slaves. When her family is captured, can she, and a boy named Crow, save them and the others?
