The 39 Clues Cahill Files: Operation Trinity

By Clifford Riley

Operation Trinity is the story of the most coveted work of art in the world, a masterpiece that has been the target of a record seven theft attempts. The adventure jumps from the first attack on the masterpiece to WWII and young Grace Cahill's desperate bid to save it from the Nazis. The final story tracks Ian and Natalie Kabra's first solo mission - and the searing betrayal that nearly costs them everything.

Rick Riordan

Riordan started his writing career with an adult mystery series set in his hometown of San Antonio, TX, but is best known for his mega-bestselling middle-grade series, Percy Jackson and the Olympians. "I think kids want the same thing from a book that adults want - a fast-paced story, characters worth caring about, humor, surprises, and mystery," says Riordan. "A good book always keeps you asking questions, and makes you keep turning pages so you can find out the answers." Riordan kicked off The 39 Clues series with Book 1: The Maze of Bones and wrote the story arc for the first series.

Gordon Korman

Korman wrote his first book when he was 12 years old. "It wasn't on purpose." He says, "In my school, the track and field coach had to teach language arts, and for writing, he just told us to work on whatever we wanted for the rest of the year." Korman sent his manuscript for This Can't be Happening at Macdonald Hall to Scholastic, and it was published in 1978 when he was fourteen. Now Korman has 65 novels to his credit, including Swindle, Zoobreak, and three installments of The 39 Clues.

Peter Lerangis

According to Lerangis, it is Jack London's fault. He was in fifth grade, reading London's short story "To Build a Fire," set in the Arctic. He began shivering uncontrollably, in a kind of fugue state, right in his suburban bedroom. Because of words! Whatever London had done, Lerangis wanted to do that when he grew up. And he's been trying ever since, with more than 160 books under his belt, including four The 39 Clues books to date.

Jude Watson

What could be more fun than writing in your journal? Well, how about writing Queen Amidala's journal? Jude Watson gained a following as a celebrated author of Star Wars novels. She is now best known for her four New York Times bestselling The 39 Clues books, and for her novel What I Saw and How I Lied, which won the National Book Award. Jude wrote the story arc for Cahills vs. Vespers.

Patrick Carman

Patrick Carman is the bestselling author of the Land of Elyon series, as well as the Elliot's Park series, the Skeleton Creek series, and the Trackers series. He is the author of The Black Circle, the fifth installment in the groundbreaking The 39 Clues series. Patrick got his start as a storyteller weaving bedtime tales for his two daughters. He lives in Walla Walla, Washington with his family. Visit Patrick Carman online at www.patrickcarman.com.

Linda Sue Park

Park's first publication was a haiku in a children's magazine when she was 9 years old. She received a check for one dollar for it, which she gave to her dad to frame and hang over his desk. A year later, the magazine wrote to Park asking her to cash the check. When she wrote back to explain where it was, they said it was okay if her dad kept it. He still has it to this day. Park went on to win a Newbery Medal for A Single Shard and to publish multiple picture books and novels, including the ninth book in The 39 Clues series and the fifth book in the Cahills vs. Vespers series.

Margaret Peterson Haddix

Margaret Peterson Haddix grew up on a farm near Washington Court House, Ohio. She graduated from Miami University of Ohio with degrees in English/journalism, English/creative writing, and history. She has written more than 20 books for kids and teens, including Running Out of Time, Mrs. Dunphrey, the Shadow Children series and The Missing series. Her books have been honored with the International Reading Association's Children's Book Award, the American Library Association Best Book and Quick Pick for Reluctant Readers notations, among others. Haddix lives in Ohio.
