The Empty City (Erin Hunter's Survivors Series #1)

From the author of the bestselling Warriors and Seekers books comes a thrilling new animal fantasy series. In Survivors, Erin Hunter shows readers the world through the eyes of dogs, as she did with cats and bears in her earlier series.
 
The Empty City begins with the Big Growl, a devastating earthquake that changes Lucky’s world forever. Lucky has always been a Lone Dog, but now he needs a Pack in order to stay alive, so he teams up with a group of Leashed Dogs who have been separated from their owners.
 
Lucky’s vivid point of view and the pulse-pounding action make for the start of an addictive series. The time has come for dogs to rule the wild!
