A boy and a moose . . .

What could possibly go wrong?


Eight-year-old Jimmy is the new kid in school and he’s already been labeled as a troublemaker. After his first attempt to make a friend has disastrous results, the only one who seems to care about him is Mortimer – a big ole clumsy moose that wanders into town causing problems of his own. Jimmy and Mortimer face one setback after another, including a run-in with a couple of bullies and an escape by the class pet. The soccer game between the teachers and the third graders might be the opportunity Jimmy is searching for. Can he and Mortimer finally prove to everyone that they belong?

If it is to be, it’s up to me!

Mortimer and Me: The Bigfoot Mystery

It all started with a huge footprint . . .

Eight-year-old Jimmy and his moose friend Mortimer join the rest of the Trailblazers on a camping trip to earn their Outdoor Adventure badge. What starts out as a team building exercise soon turns into an investigation of a mysterious footprint that can’t be described as animal or human. What kind of creature made it and where did it go? One discovery leads to another, until no one knows what to believe anymore. But one thing is for sure . . . they are not alone.

Take only memories, leave only footprints.

"I was looking forward to seeing what new adventure Jimmy and Mortimer would have in the sequel, Mortimer and Me: The Bigfoot Mystery. In this story, Mortimer and Jimmy join the Trailblazers and head to the woods to earn their Outdoor Adventure badge. Of course, there are many surprises throughout the trip, and the reader is never sure what they might find next. A great story for elementary students and a fun, exciting read-aloud for teachers."

"Mortimer and Me sparkles with humor and high jinks. Young readers are sure to relate to third grader Jimmy Robertson, whose good intentions always go awry. . . Like Jimmy, Mortimer just doesn't quite fit in with the others. But as these two unlikely companions bounce from one adventure to the next, a genuine friendship develops, one that will keep readers eager to see what happens next."

"Jimmy's dad and his friend Justin's father form a third-grade scout group called the Trailblazers. While working on their Outdoor Adventure badge, the Trailblazers find evidence that a large creature with enormous footprints lives in the woods. Despite difficulties getting along with each other, the scouts learn to work as a team, and "aided" by Jimmy's moose friend, Mortimer, solve the mystery -- or do they? McMahon crafts this story with equal parts of suspense and humor."
