The year is 2019 and a secret government agency is forcing Eli's dad to continue with his time-travel experiments, even though Eli's mom has just disappeared in one. Now Eli has a ridiculous new code name — and a gravely important mission. In this first episode in the exciting Danger Boy series, a lab accident sends Eli sprawling through the Fifth Dimension, where he hooks up with the amiable Clyne, an evolved dinosaur from an alternate Earth who just wants to finish his homework. Clyne's timeship lands them in ancient Alexandria, Egypt, just as a great fire rages through the city, and the girl scientist Thea is fleeing an angry mob who thinks she's a witch. As if that's not enough, in the present-day world, a deadly pox is on the loose, and bizarre things are starting to happen to the fabric of time itself.

"This cleverly plotted, engrossing read will appeal to maturing fans of Jon Scieszka’s ‘The Time Warp’ series." — SCHOOL LIBRARY JOURNAL Fresh from a dangerous time-traveling mission, Eli Sands and his friends Clyne, the dinosaur, and Thea, the scholar from Alexandria, are thrown into nineteenth-century America. While Clyne is stranded alone, Thea and Eli pop up at the start of the Lewis and Clark expedition, where Thea is mistaken for a runaway slave. After a close escape, the friends make an unsettling discovery about a Prime Nexus that they may have caused — and which will surely change all of history to come.

"Readers will revel in the fractured time line, as well as in Eli’s ruminations on relativity, unintended consequences of technology, and quantum flux." — SCHOOL LIBRARY JOURNAL After another close call, Eli Sands, aka Danger Boy, is back in San Francisco in 2020. The bad news is that he and his friends, Clyne and Thea, are being held captive by the government agency DARPA. Since their last foray into the Fifth Dimension, history has been unraveling, the deadly slow pox is spreading fast, and DARPA wants to send Eli back in time to ancient Jerusalem. But Eli and crew discover a city in ruins from a Babylonian invasion and an angry mob ready to stone them. Will Danger Boy and company ever find their way home again?

Weeks after watching her principal try to chew up her teacher, and minutes after she'd just lost her family, 12-year-old Aurora Bonsall begins her escape. Alongside Max Random in his hand-built go-kart, they set off across a ruined landscape of studio backlots, wrecked shopping malls, and not-so-abandoned hospitals. At every step, they'll find the not-quite-dead waiting for them. As they head for a rendezvous point where Max insists they'll be safe, it becomes clear that surviving humans can be far more dangerous than the Nano-Zs taking over the world. But as Aurora discovers Max has secrets of his own, she wonders if there can ever be any escape at all.
