From the author of the highly acclaimed Ink, Iron, and Glass series, this YA duology sends three science prodigies on a time-traveling adventure to save the Earth—if they don’t accidentally destroy it first—in Gwendolyn Clare's In the City of Time. In 1891, Willa Marconi's life falls apart when her mentor at the University of Bologna unexpectedly dies. She loses her laboratory access and her stipend, but she refuses to let anyone take her research away. While testing her prototype radio equipment, she detects a mysterious signal and pursues its origin. In 2034, a cataclysmic event has rendered the Earth uninhabitable, and humankind survives by living inside of artificial worlds. Riley would do anything for Jaideep, who lost his parents in the collapse of the Bay Area pocket universe—and anything includes building a time machine so they can travel back to the 19th century, prevent the destabilization of the planet, and rewrite history. But the experiment goes wrong, accidentally pulling Willa forward in time and stranding the three of them in a strange, seemingly abandoned city. Now they’ve got a glitchy time machine, a scary android time cop hot on their trail, and some tangled temporal mechanics to unravel. Can they save the Earth when the Continuity Agency is dead-set on preserving the current timeline?

In this heart-pumping sci-fi sequel to In the City of Time, two people have to work together to prevent the cataclysm that will soon break the laws of physics and render Earth uninhabitable. Now in possession of the most dangerous book ever scribed, Willa and Saudade settle into the nineteenth century and start planning how to avert the cataclysm that will soon break the laws of physics and render Earth uninhabitable. Faraz only wants his best friend, Leo, to have the time to come to terms with the death of his father—even if his father was a power-hungry villain who had to be stopped. But someone has stolen the editbook again, and now Faraz and his friends must track down Willa and challenge her for control of the editbook. Meanwhile, Leo’s older brother Aris contemplates a path toward redemption after using the editbook to destroy the city of Napoli. Can he salvage his remaining relationships, after a lifetime of following their father? But as far as Willa and Saudade are concerned, all these people are suspects in a crime that hasn’t happened yet.

In this thrilling debut, worlds collide as Elsa unveils a deep political conspiracy seeking to unlock the most dangerous weapon ever created-and only she can stop it. Can she write a world gone wrong? A certain pen, a certain book, and a certain person can craft entirely new worlds through a branch of science called scriptology. Elsa comes from one such world that was written into creation by her mother-a noted scriptologist. But when her home is attacked and her mother kidnapped, Elsa is forced to cross into the real world and use her own scriptology gifts to find her. In an alternative Victorian Italy, Elsa finds a secret society of pazzerellone-young people with a gift for mechanics, alchemy, or scriptology-and meets Leo, a gorgeous mechanist with a smart mouth and tragic past. She recruits the help of these fellow geniuses just as an assassin arrives on their doorstep.
