One moment, Boomer and Matilda were playing with their friends in the bush in Australia, and the next, they were being transported to the Ellen Trout Zoo in Lufkin, Texas! Boomer, a kangaroo from New South Wales, Australia, and Matilda, a koala bear from Queensland, Australia, had never traveled out of their homeland. On the final leg of their journey, the truck in which they were being transported spun out of control in a violent rainstorm. As a result, the truck flipped on its side and slid for several yards before stopping. Their cages were tossed about inside the truck, and when the truck stopped sliding, the doors of their cages sprang open, as did the doors to the truck itself. Boomer and Matilda, shaken but uninjured, found themselves in an unknown land, in a bad storm, and in the dark.

They were frightened, tired, hungry, and lost!

Little did they know at the time, but they were going to be tracked by the zoologist responsible for their transport to the zoo and the Texas State Trooper trying to solve the mystery of the truck accident. And as if that weren't enough, an overeager reporter seeking fame by "saving" the community from wild animals was also hot on their trail.

Two escaped "wild" animals, an eager reporter, a confused zoologist, and a determined state trooper all cross paths in this first adventure of Boomer and Matilda. They were about to embark on an adventure that will forever change their lives!
