Scurry Book 1: The Doomed Colony by Mac Smith

Scurry is the story of a colony of mice in an abandoned house who are struggling to survive a long, strange winter. The humans are all gone and the sun is rarely seen. As food becomes scarce and many mice fall ill, the scavengers are forced to search farther from their home, braving monster infested lands in search of anything that will help the colony survive another day. Being hunted by feral cats and predatory birds is part of life for these mice, but beyond the fences stalks something far more fearsome...
