More from Karen

Are you a dog-lover? I sure am. Have been since I was a child, often referring to my 110-pound silver-tipped German Shepherd as my ‘best friend’ in elementary school. I consider dogs the finest companions and treat our own like they are family. Because they are! Well, I am pleased to introduce a new character in the third book in the Questions for Kids series, and she is a special one. Meet Rosie, the spirited Golden Retriever puppy hiding under the covers with Lucy, scared of the summer thunderstorm rumbling outside. It made sense to bring Rosie into the series with this book, because animals are an important part of this story. Rosie is extra special because she’s modeled after my youngest daughter’s dog, who I helped care for in her first of year of life. Here she is!

Guess Why God Made the Rainbow takes young readers on another exciting adventure into the Bible, this time going back to Noah’s Ark. Children will encounter God as the Promise Keeper and understand why He made the rainbow.

My goal with this book series is to promote biblical literacy in this next generation. Helping young readers engage with God’s truth through some of the most foundational Bible accounts essential to building a strong faith in an all-powerful, all-knowing, and all-loving God. Each adventure takes young readers into unique periods of Bible history, driven by curious Lucy’s earnest questions to her Papa Joe. It’s designed to captivate young readers and connect the Bible to their world. It’s also a great tool to spark spiritual conversations between kids and their parents, grandparents, caregivers, and teachers.

The first three books in the Questions for Kids series cover the Creation account, the first family in the Garden, and Noah building the Ark, with at least four more coming soon! I pray this new book and series is a blessing to you and your young reader.

Author Interview

Can you tell us a little bit about what readers can expect from your books?

In the Questions for Kids series, readers can expect to experience the wonder of the Bible through exciting adventures right alongside the main characters, Lucy Lu and her trusted advisor Papa Joe. Each book transports readers back to a unique period in Bible history, exploring the people, places, and events that help shape a strong faith in our God and His never-changing, never-failing, and never-ending love.

Can you share 5 random facts about this book?

Lucy and her new puppy hide under the covers afraid of a summer thunderstorm. A beautiful after-storm rainbow leads Lucy and her Papa Joe back to the time of Noah’s Ark. There were only eight people on the Ark. The rain lasted 40 days, but they didn’t leave the boat for many months. Lucy learns the real meaning of the rainbow and that God’s promises can always be trusted.

What was the inspiration behind it?

This book series goes through the Bible chronologically, so the choice was simple to go with Noah’s Ark for book three, because it was the next ‘big’ Bible account important to help grow young readers’ biblical literacy. We’re also living in a time when it’s important for kids to understand the real meaning of the rainbow. 

What was the most rewarding part of bringing this book to life?

The first part of writing each book is finding a story thread that will connect readers to Lucy and to the Bible, which I find rewarding. In this case, I felt that a rainbow after the storm would be a perfect segue back to Noah’s Ark. Having lived in the south now for four years, I’ve seen more intense storms here than my whole life growing up in the Pacific Northwest. And I’ve seen how unsettling it can be for dogs and children, and even adults sometimes! 

What do you hope readers will take away from the book?

My hope for every book in this series is to point children to God’s truth in the Bible, and to help them understand His faithfulness over the generations to His people, and His never-changing, never-failing, and never-ending love.
