"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.
