American Marconi Wireless News - Noted Children's Co-Authors David And Emberli Pridham Launch All-New Kids' Chapter Book Series If Not you then Who?: Who Turned Off the Lights? (If Not You, Then Who? Mystery Book 1)

DALLAS, TX / ACCESS Newswire / April 2, 2026 / Husband-wife kids co-authors David and Emberli Pridham - who gained national recognition for their award-winning children's picture book series If Not You, Then Who? - continue on their mission to introduce grade schoolers to the world of invention with the launch of their all-new fun and action-packed adventure chapter book series, If Not you then Who?: Who Turned Off the Lights? (If Not You, Then Who? Mystery Book 1).

Now available, If Not you then Who?: Who Turned Off the Lights? takes young readers on bold and thrilling adventures into history as they join the Sparks family on secret missions to confront the villainous Emperor Entropy, the family's arch enemy who seeks to undo the milestone achievements of the world's great inventors. In the first chapter book, Brooke, Noah, Graham, and Lily Sparks together with their scientist parents travel to 1880 to protect one of the most important inventions of all time: the electric light bulb. When the world suddenly goes dark, replaced by candles and gas lamps, the kids know it must be their old enemy Emperor Entropy, once again meddling with history. This time, Entropy stopped Thomas Edison from inventing the light bulb, leaving future generations in darkness. With the help of their scientist parents and their lovable robot dog, Chronos, the Sparks kids race to Menlo Park, New Jersey, to find Edison. But they discover he's abandoned the light bulb for a frivolous gadget. Now, it's up to the Sparks siblings to rekindle his spark of ingenuity before Emperor Entropy succeeds in erasing electric light forever.

Each story in the Pridhams' chapter book series explores what life would be like if an important invention had never been created-while the Sparks kids show how curiosity, creativity, and courage can save the day. Packed with adventure, humor and real history, Who Turned Out the Lights? is co-authored by David and Emberli Pridham, and illustrated by Danilo Ceravic.

As children read the If Not You, Then Who? books, they will discover how inventors take note of the problems people face in their daily lives and help solve them through creativity and innovation. And along the way, the Pridhams share ways in which kids can embark on their own journey of invention and work to help build a better world.

If Not you then Who?: Who Turned Off the Lights? (If Not You, Then Who? Mystery Book 1) is available in on the If Not You, The Who website (www.ifnotyoubooks.com), through all online bookstores and on Amazon via Kindle.
