Life after the undead by Pembroke Sinclair.
Seventeen-year-old Krista must quickly figure out how she’s going to survive in the zombie-destroyed world. The one advantage humans have is that the zombies hate humid environments, so they’re migrating west to escape its deteriorating effects. The survivors plan to construct a wall at North Platte to keep the undead out, and Krista has come to Nebraska to start a new life.
A really enjoyable read. Krista was my favourite character. Can't wait for next part. 5*. Netgalley and booktrope.

I tried to read this book,on several,occasions, but kept putting indies because it just made no sense that they could travel such long distances and not be bothered by other survivors nor zombies. I have read a lot of zombie books, and it is all often unbelievable, but the lack of anything going on during the back & forth just kept bothering me.
