In 1903, five truly brilliant young inventors, the children of the world’s most important scientists, are taken from their lives and their parents by the mysterious men in black. They take twelve-year-old Jasper and six-year-old Lucy Modest from London, England; nine-year-old Wallace Banneker from New York, United States; twelve-year-old Noah Canto-Sagas from Toronto, Canada; and thirteen-year-old Faye Vigyanveta from New Delhi, India, depositing them all at a strange, isolated farmhouse in Dayton, Ohio, with kindly schoolteacher Miss Brett. But what mysterious invention have all the children, unbeknownst to one another, been working on? Who are the men in black? And are the men in black trying to kidnap them—or protect them? And if they’re trying to protect them—from what?

An amazing story about the wonders of science and the still greater wonders of friendship, The Atomic Weight of Secrets or the Arrival of the Mysterious Men in Black, the first book of the Young Inventors Guild trilogy, is a truly original novel. Young readers will forever treasure Eden Unger Bowditch’s funny, inventive, poignant, and wonderfully fun fiction debut.
