Having lost the Pearl to the evil Cult of Wardenclyffe, Olivia must face life without the most powerful device in the universe. Pursued by the paparazzi in their quest to get the true story of the Bear Girl, she must learn to trust and rely on other people if she is going to rescue her brother Gnat and best friend Doug who are lost in ancient Florida; never mind finding her missing parents or ending the environmental catastrophe she caused.

 Hospitalized with mysterious pains, Olivia meets Nigerian-born Abiona, a math-whiz with a deep secret. Together with fun-loving Terrilyne, they decide to release the Bobwhite witch from her frozen tomb in the hopes she can restore everyone’s lives back to normal. What they unleash is beyond anything they could have imagined. Confronted by the true power of the Pearl, Olivia must make a choice that will alter the direction of the earth and her future.

“Aristotle’s Lantern is such a great addition to the series and an amazing book for young readers.  As a young reader myself, it’s a struggle finding appropriate books that also challenge my reading.  This book is all of those things and more.  It is brimming with adventure and a little bit of mystery to keep readers on their toes.  Olivia is such a fierce and lovable character.  I love seeing how her mind works and how she faces all the challenges that are thrown at her, Hoolie, and friends.”  -- Sophia Papadakos, grade 7 

“I could relate to so many things Olivia felt. You wrote an amazing book and I think the world should get the chance to read it.” – Helen, grade 5

“I will be using this book in my classroom to integrate Language Arts skills and science teaching. The students will use this book as a starting point for writing research papers, poetry, and oral presentations.” – South Carolina teacher



Olivia Brophie feels betrayed. She hasn’t heard from her mom who’s serving in the army in Iraq. And for no reason, her dad sent her to live with her crazy aunt and uncle in the middle of nowhere—the Florida scrub. It seems boring till bears follow her to school, coral snakes leave her gifts, and tree frogs start writing cryptic messages on her bedroom window.

Olivia is fascinated by the giant insect walkingsticks that her uncle tenderly protects. He turns out to be crazier than she thought with wild ideas about magnetic currents, cosmic rays, and a mysterious device that controls the laws of the universe. He doesn’t know the half of it.

Along with Doug, a local eco-nerd genius, and Gnat, her videogame-obsessed little brother, Olivia discovers a vast underworld city that holds the secrets of history as well as the way to the future. With the forces of evil at her heels, she finds a brilliant pearl and must use its power to discover her life's ultimate destiny.

Olivia’s life is in turmoil ever since she accidentally froze all of the world’s water and her aunt and uncle were kidnapped by the Wardenclyffe thugs. With the help of a black bear named Hoolie, she must travel across America to restore the damage she caused. Hungry and wounded, she stumbles into a secret valley invisible to the outside world. There she encounters an ancient civilization with no intention of letting her leave.

In the meantime, Doug and Gnat are drawn deeper into the world of Junonia, the mysterious city built in the aquifer beneath Florida. As Doug works diligently to scientifically document the discovery of giant tardigrades, he meets his old nemesis, a bully who manages to start a war among the tribes of the aquifer. Caught in an epic battle, Doug must find a way to save himself, Gnat, and the bully who doesn’t want his help.

Olivia Brophie and the Sky Island is a fast, action-packed ride through fantastical landscapes
populated by long forgotten real-world elements. Chris Tozier has created a compelling mix of
intrigue, danger, and magic that will keep readers turning until they've reached the last page.”
