I like the Dangerous Days books by Baileigh Higgins, but at the moment I'm reading the Orphans series by Mike Evans. I read the first half a dozen books a few years ago, but missed the last couple, so I'm doing a reread to catch up before I start the new ones.

It's about a load of kids who survive the initial outbreak, but their parents don't. The kids have to learn to survive on their own against fast zombies, while not starving, or dying from avoidable things.

It's a good series 👍
