About this item

Eleven-year-old Luis is left looking for answers after a city-wide blackout leads him to an electrifying mystery in this edge-of-your-seat thriller from Martha Freeman.

Luis Cardenal is toasting a Pop-Tart when a power outage strikes Hampton, New Jersey. Elevators and gas pumps fail right away; soon cell phones die and grocery shelves empty. Cold and in the dark, people begin to get desperate.

Luis likes to know how things work, and the blackout gets him wondering: Where does the city's electricity come from? What would cause it to shut down?

No one seems to have answers, and rumors are flying. Then a slip of the tongue gives Luis and his ex best friend Maura a clue. Brushed off by the busy police, the two sixth graders determine they are on their own. To get to the bottom of the mystery, they know they need to brave the abandoned houses of Luis's poor neighborhood and find the homeless teen legend known as Computer Genius. What they don't know is that someone suspects they know too much, someone who wants to keep Hampton in the dark.

In this electrifying mystery, two can-do sleuths embark on a high-tech urban adventure to answer an age-old question: Who turned out the lights?

About the Author

Martha Freeman

Martha Freeman was born in Southern California in 1956. Dinosaurs were no longer a threat at this time. Do not listen to her three children when they try to tell you differently.

After graduating from Stanford University, Martha worked as a newspaper reporter, copy editor, substitute teacher, college lecturer, advertising copywriter, and freelance magazine writer before she found her true calling as a writer of children's books. She has since published 23 books for children. She is a very busy person.

In 1995, Martha's family moved from Sonora, California, to State College, Pennsylvania. Martha's book, "The Year My Parents Ruined My Life," is loosely based on this move. In fact, Martha's books are often inspired by her family. You can see how watching many, many, many Little League and Babe Ruth baseball games has influenced her writing if you read her popular mystery, "Who Stole Uncle Sam? "

Pets - especially cats - have always been important to Martha. That's why almost every single one of her books has a cat as a character, and her First Kids mysteries feature a first dog with too much energy, Hooligan.

Martha currently lives in Philadelphia, Pennsylvania, where she enjoys running, parallel parking, making pies, and babysitting for her neighbors' baby... besides writing, of course.
