Lexa Andromeda is just a normal twelve-year-old girl, until the day her dog dies.

She's at a loss—until she discovers pranking. It's fun, it's easy, and it gives her something to do while she mourns. But when one prank goes too far, Lexa finds herself sent to Thistleton Academy—a prestigious boarding school for "Highly Creatives" like her.

And that's when things start getting weird. Lexa soon discovers a sinister plot that could lead to a mass extinction event. Join Lexa, her friends, and a mysterious time traveler as they navigate the dangerous halls of Thistleton and work to reveal the truth and save the world before it's too late.
