About Peter

Peter Vanderwall based Mac’s Big Wish on a bedtime story he created to tell his sons, Eric and Kenny, when they were growing up. The story was inspired by his first encounter with a therapy dog many years ago. Trooper comforted Peter’s mother and the other residents of a memory care center in upstate New York. The story was also inspired by his rescue of Sandy, a Yellow Labrador, who he found as an abandoned puppy wandering in the morning fog and who became a lifelong companion. Mac’s Big Wish is the first in a series of children’s picture story books to be published by Sophie & Sheba Books.


Peter is a screenwriter whose produced movies include Hide Away starring Josh Lucas and James Cromwell, Reverse Angle, Shadowheart, and Without Evidence, all available on Amazon Prime. His action thriller, Shore Excursion, is in pre-production for filming in the Greek isles.


Peter and his wife, Kathleen, share their time between the Pacific Northwest and Utah where they enjoy skiing, hiking, biking, kayaking, and other outdoor adventures.

Mac's Big Wish.

2022_10_15 Kirkus Review.png

October 15, 2022   A dog learns that each pup is special in their own way in Vanderwall’s debut picture book. Vanderwall builds the story well for newly independent readers, with simply structured sentences, repeated phrases, and fun sound words (squish-squash-squish, click-clack, squeak-squeak-squeaking). Illustrator Lillian’s two-page spread is joyful. The painterly cartoon style allows for humanlike expressions on otherwise realistically portrayed animals’ faces, and the diverse cast of humans of varying skin tones, shapes, and ages is a delight.  A book for dog lovers featuring a strong lesson about the value of friendship.

Thank you for sending the five signed copies of Mac's Big Wish. Such a beautiful book with many important lessons for my grandchildren. It is likely when their books are passed down to their children they may relate our story to them!

I shall encourage that!

Beautifully written and gorgeously illustrated, this book is a hidden treasure waiting to be found and passed down for generations.
It's a story that will not only capture children's hearts but anyone's heart no matter how old you are. Mac's journey takes you through the emotions that we all experience. Loneliness, sadness, fear, hope, happiness, and pure joy. This story reminds us that dreams and wishes really can come true, and that no matter what,
there is always hope.

Free Lessons developed by classroom teachers


Dr. Susan Inman was astonished by how Mac's Big Wish could help elementary students focus on
the moral of the story and other important concepts of literacy. As a school improvement specialist
and adjunct professor at Bushnell University, she found that the expressive animals in
Mac's Big Wish helped young students understand difficult concepts like optimism
and offering help. 
As a professor of classroom teachers learning advanced techniques, she asked teachers to consider the developing lessons based on Mac's Big Wish. 
Elementary teachers in Dr. Inman's classes developed the lessons linked below. These freely contributed lessons give all teachers -- and other adults in childrens' lives -- ideas and structure. Download the lessons free-of-charge. The lessons are open source. The PDFs, maintain original formatting, are good for printing. The RTFs are great for adapting lessons for your own classroom, by letting you make revisions on most word processors.
