The Sparks kids have a secret: they can travel back in time! But their adventures aren't just for fun-they journey into the past to save the world's greatest inventions.
In Who Turned Off the Lights?, Brooke, Noah, Graham, and Lily Sparks 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 their old enemy Emperor Entropy is meddling with history. He has stopped Thomas Edison from inventing the light bulb, threatening to leave future generations in darkness.
The first book in an adventure-packed new chapter book series from the creators of If Not You, Then Who?

About the Authors
Emberli Pridham grew up in Dallas, Texas, inspired by her grandmother, an author, and by a wonderful library of books. Along with her husband, David, she co-authors the Amazon best-selling STEM series If Not You, Then Who?, which teaches children about the inventions and patents in everyday life, empowering them to imagine and create their own.
She is also the author of Real-Life Fairy Tales, a children's series that includes Princess Diana: A Real-Life Fairy Tale; Princess Grace: A Real-Life Fairy Tale; and Jacqueline Kennedy: A Real-Life Fairy Tale. Each book chronicles the inspiring lives of renowned women who rose from relative anonymity to become global icons, leaving contributions that changed the world.
Pridham's lyrical tone and subtle rhymes shape her writing style, helping young readers stay engaged as they move from page to page. As a designer, she also pays careful attention to the look of her books, with Real-Life Fairy Tales featuring watercolor-inspired illustrations that bring the stories to life.
The Pridhams live in New England with their three children-Brooke, Noah, Graham and Byrdie.
