"Young readers will find plenty to like here, from the fast-moving plot, to the characterizations of individual dogs. A promising start for the many fans of the Warriors and Seekers adventure series."--Booklist

"Hunter expertly explores the tensions between responsibility and freedom; risk and safety; and loyalty and acceptance. Viewing the unfolding adventure through Lucky's eyes makes even the most mundane or familiar seem alive with magic. Wild and wonderful adventure for middle-graders."--Kirkus Reviews (starred review)

In a brand-new animal fantasy series from the #1 nationally best-selling author of the Warriors and Seekers series, humans have disappeared and a new animal is ready to rule the wild, but which animals will be brave enough to step up and take control when a strange disaster strikes? 150,000 first printing.

Lucky is a golden-haired mutt with a nose for survival. He has always been a Lone Dog, relying on his instincts to get by. Other dogs have Packs, but Lucky stands alone.

Then the Big Growl strikes. Suddenly, the ground is split wide open. The Trap House is destroyed. And all the longpaws have disappeared.

Now Lucky is trapped in a strange and desolate new world with no food, foul water, and enemies at every turn. He falls in with others left behind, including his littermate Bella, a Leashed Dog. Relying on other dogs?and having them depend on him?brings new dangers that Lucky isn't prepared for, but he may not be able to survive on his own. Can Lucky ever be a true Pack Dog?

Erin Hunter is inspired by a love of cats and a fascination with the ferocity of the natural world. In addition to having great respect for nature in all its forms, Erin enjoys creating rich mythical explanations for animal behavior. She is also the author of the Seekers, Survivors, and Bravelands series.
