What would you do if you were trying to survive a zombie apocalypse and came across a note asking for your help?

That’s the issue facing the main characters in “Z Notes,” a new novel by author Shawn L. Lilly.

Lilly describes the book as a “quest for survival and freedom.”

“Two friends find themselves trapped in a world turned upside down, where fighting is what you do just to stay alive one more day,” Lilly explained. “Matt and Frank make it by looking out for each other. But their lives are flipped once they come upon a note for help. Now they are off on a quest to find the person who wrote the note, killing every undead in their path.”

Published by Newman Springs Publishing, Lilly’s nerve-wracking tale unravels a story that transcends the natural and breaks the barrier between living and dead.

Readers who wish to purchase “Z Notes” can find it at bookstores everywhere, or online at the Apple iBooks Store, Amazon, or Barnes and Noble.
