Ninjas vs. Zombies by Justin Timpane

4.10

Seven friends, struggling with late 20s, early 30's life, find themselves in terrifying danger when a long-dead loved one is magically resurrected and starts devouring souls. To make matters worse, three of them have been granted the power of the Ninja, and now must lead the fight against a power they cannot hope to vanquish. If they fail, the un-dead will overrun their little town, and quite possibly the world.
