Overview
A laugh-out-loud, edge-of-your-seat time-travel adventure perfect for fans of The Last Last-Day-of-Summer and City Spies from New York Times bestseller, Krystal Sutherland. Twins Pearl and Patrick are no ordinary twelve-year-olds. They’re geniuses, hiding in plain sight, who pull heists all over the world to further their scientific and historical research. Their criminal activity, including grand theft auto and espionage, has made them a regular nuisance to both the CIA and MI5. But it’s all been worth it. They’ve finally achieved their greatest triumph: time travel. Pearl’s Chrono-Loop can take the twins anywhere in time! Their first stop: ancient Egypt, where they even get to see King Tut! But when they return home, they’re arrested by TIME—The Interdimensional Misconduct Enquiry—a secret organization charged with maintaining the timeline. Turns out Pearl and Patrick didn’t invent time travel, after all—that happened two hundred years ago! And what Pearl did in ancient Egypt—killing a mosquito—could have rewritten history as we know it if not for TIME agents stepping in. Punishment for disrupting the timeline is 100 years in the Eternal Abyss. But TIME, impressed by the pair, offers them a chance to become agents. Unfortunately, they fail their entrance exam and instead are banned from ever attempting time travel again. Pearl is furious, and when she’s offered another chance at time travel by a rival organization, she takes it! Too late, she realizes she’s been tricked and unwittingly plays a part in replacing the timeline they know with a nightmarish scenario. Now Pearl and Patrick must clean up the mess they’ve made. But to restore the timeline, they have to go back to the beginning—to Lion Rock—to convince the real inventor of time travel to help them save time and the world. In this electric time travel adventure steeped in unexplored Sri Lankan history, these whiz kids use their book smarts and a healthy dose of girl power to fight the ultimate villain.

Praise for Time Lions and the Chrono-Loop: ★ “In this immersive sci-fi fantasy series launch…Seneviratne and Sutherland reference real historical figures and events to ground intricate, fantastical worldbuilding, and deploy strong characterization chops to develop fully fleshed-out protagonists. The siblings are complex and undeniably charming tweens, whose journeys…make for a vivacious time-hopping extravaganza.”—Publishers Weekly, starred review
Author Information
After marrying in late 2019, Krystal Sutherland and Martin Seneviratne immediately decided to put their vows to the test by collaborating on their debut middle grade series, Time Lions. Martin’s childhood was infused with his grandmother’s magical tales of Sri Lanka’s history and mythology. On a visit to Sigirya, the ancient rock fortress in the heart of Sri Lanka’s jungles, Krystal and Martin began to craft this story of the genius Amarasinghe twins and their adventure back through time. It explores overlooked parts of history and the overlooked geniuses who shape it.
