Monsters by Ilsa J. Bick (author) (UK edition)

Alex is tough. She has survived the EMP blast, she has lived among the flesh-eating Changed, and she has been separated from Tom for months. And she hasn’t given up.

But on the brink of starvation and in the grip of a winter that just won’t end, Alex discovers a new and terrible truth:

The Changed are still evolving.

And… they’ve had help.
