The Story behind the Story

New ideas for children’s books often arise when I am walking in the woods with my dogs, when I am out sailing on the water or while I am enjoying cups of fresh ginger tea. During these mindful moments, I have some time to not think at all… just wonder, be amazed and let my imagination run freely… This is also how I came up with the idea for my latest book in which a boy finds an egg. The boy takes the abandoned egg home and has the wildest fantasies about what will come out… Will the hatched animal be the friend he had imagined?

Early Reviews

“An incredibly charming story about discovery, research, and the power of curiosity in young people. Highly recommended.”
– Rogene Carter (Educator)

“Cute and fun story about acceptance and tolerance. There is humor but also a good message and all of it is well illustrated. Good job!”
– Etienne Breton

“Well, that was too cute! The Boy and the Egg is a short, adorable read with precious whimsical illustrations! I will be honest and say that I chose this book based on the illustration style alone. But the story ended up being just as whimsical and sweet. With bright colors, an engaging storyline, and child-like curiosity, this story will engage even the squirmiest of little ones! I highly recommend this, and will likely grab a hardcopy as soon as it's available!”
– Sarah Grace Grzybowski
