JOIN THE PROTEST. JOIN THE MAGIC. After her sister disappears during a climate protest, seventeen-year-old Mira Bracken spends her days combing an uncaring world for any trace of her. She's handing out missing-person flyers at the latest climate protest when an SUV terrorizes the crowd, plunging towards the strikers and heading directly at Mira. Without warning, a giant oak tree falls onto the car, saving the screaming youth in its path. A mysterious stranger insists that Mira somehow commanded the oak to act, that she's a Treetalker, a powerful one, and that an ancient order of evil men will be coming for her. She laughs it off, until the stranger adds one last thing-these men have been kidnapping youth climate strikers. Desperate to learn more, Mira throws her lot in with the mysterious stranger and the other Treetalkers. Soon she's swept into a secret magical war that spans centuries and the globe, getting closer and closer to discovering the fate of her sister.
