Adventure to Echo Falls (30 Echo Book 1)

Plucky inventor and aspiring hero Jet Chow was ten when the world (as we know it) ended in a flood of shuffling undead bodies. The zombie plague ceased with the dispersal of a cure, but society collapsed, and humanity became an endangered species. Orphaned in the disaster, Jet survived for over three years in a prepper's off-grid shelter in a Wichita backyard. When his resources run out, he is forced into a quest for food and shelter, which turns into a search for the rumored last outpost of humanity: Echo Falls.
