The Chronicles of Nick: #2 Invincible

Product Description

They say when you're about to die, you see your entire life flash before your eyes.
They lied.
When teenager Nick Gautier is saved from almost-certain death by a mysterious warrior, he has a feeling his life is about to change. Fighting the undead has taken the place of fighting with his teachers (well...almost).
But just when he thought things couldn't get any worse, he wakes up to find himself enslaved in a world of shapeshifters and demons out to claim his soul. If he doesn't learn how to raise the dead by the end of the week, he will become one of them...
