Youngblood by H. Peter Alesso

Could you survive?
……….In the 22nd Century?
………………..After an apocalypse?

Youngblood was eighteen when his father placed him in hibernation to await a cure for his disease. But when he woke a century later, he was gasping for breath in a deserted underground bunker.

Seventeen-year-old orphan, Kira, was a kick-ass huntress who knew how to survive in this environment. So, when Youngblood was attacked by survivalists, she saved him and together they struggled to unite people while searching for the remnants of their past civilization and a cure for his disease.
