My first middle grade novel, a historical mystery written with Ruta Sepetys!

Summer, 1940. Nineteen-year-old Jakob Novis and his quirky younger sister Lizzie share a love of riddles and puzzles. And now they’re living inside of one. The quarrelsome siblings find themselves amidst one of the greatest secrets of World War II—Britain’s eccentric codebreaking factory at Bletchley Park. As Jakob joins Bletchley’s top minds to crack the Nazi’s Enigma cipher, fourteen-year-old Lizzie embarks on a mission to solve the mysterious disappearance of their mother.

The TRUE STORY section

Here's where I've spend most of the past 20 years, work wise. My goal has always been to create nonfiction that's as fast paced and page-turning as any novel. The version of Bomb with the blue cover is a graphic novel - an adaptation of my narrative nonfiction book, with amazing comics by Nick Bertozzi.

Stuff they never let me put in textbooks!

These are my first three nonfiction books, written while I was making my escape from the textbook world. Basically, I tell the story of the American Revolution, the Civil War, and America's westward expansion, packing in all the true stories editors would never allow into boring textbooks.

My chapter book series: TIME TWISTERS!

Okay, these are clearly not nonfiction. They're comedy adventure stories, starring real people from history - but not quite doing the stuff the textbooks say they're supposed to!

RABBI HARVEY graphic novels

These are the adventures of a rabbi in the Wild West, based on classic Jewish wisdom and folktales. The first Harvey book, The Adventures of Rabbi Harvey, was the first book of mine to be published!
