Operation Red Jericho (The Guild of Specialists)

For Joshua Mowll, it was the surprise of a lifetime. There, among the archives inherited from his great-aunt Rebecca MacKenzie, was a 1920s journal recounting the thrilling and dangerous adventures of fifteen-year-old Rebecca and her younger brother, Doug, in the wake of their parents' mysterious disappearance in the deserts of China. Now carefully re-created in a lavish volume — complete with cloth binding and a journal-style elastic clasp — the siblings' tale begins aboard the Expedient, their uncle's enigmatic research ship, and moves at a breathless pace through the streets of Shanghai and on to a terrifying island fortress. Along the way, Doug and Becca encounter an ancient order of Chinese mercenaries, a brutal pirate warlord, a feisty Texan heiress, and a stolen cache of a volatile explosive called zoridium.
