Even heroes need a vacation. Unfortunately, Hannah and her friends chose the wrong beach. The Oracle needs help. She's dying, and only Ezekiel knows that the world will die along with her. Hannah and her team take up the call without hesitation. The only problem? It takes a freaking long time to cross the world. While putting their quest on hold for a much needed rest stop and resupply, Karl, Hadley, and Laurel get captured by some angry locals, who accuse them of kidnapping their leader's son.

Hannah and Ezekiel dig deeper into the corruption of the Noble Quarter, and the sick truth of Adrien’s master plan becomes clear. They need to call upon the diverse group of those loyal to the cause in order to stop the Chancellor’s reign of terror--before any more innocents die by his hand. Meanwhile, Karl and Parker enlist a powerful ally to help them battle against the Prophet’s lies, and Gregory prepares for something far more dangerous than battle--a formal ball at his parent’s house.

Hannah killed those who destroyed her family, but the man who ordered their deaths is still alive - and in power. It's time someone worked to end Adrien's evil rule. But to find justice, Hannah needs to increase her skills. She and Sal head to the Heights for a little one-on-one training with a handsome young mystic while Ezekiel heads north to right a 40-year-old wrong. Meanwhile, Parker is stuck dealing with the mess left behind after Hannah's ass-kicking.

Magic’s biggest secrets are finally revealed. After weeks of travel aboard the Unlawful, Hannah and Team BBB make it to their destination on the far corner of the known world. New Romanov. The home of the Oracle. And they arrive not a moment too soon as the evil forces bent on Irth’s destruction launch another attack. Hannah’s new enemy is bigger and badder than anything she’s encountered, and it is going to take all the power of her team - and more - to stop it.

The quest to save the Oracle forces Team BBB to split up: one group heads to the top of an ancient mountain, the other into the depths of a haunted jungle. For Hannah, it’s an all out fight that pushes her magic to the limits, while Karl is tasked with something far more challenging - diplomacy. Both groups will need to depend on the strength of their teammates, while cautiously navigating the cultures and practices of strange, new inhabitants of the furthest reaches of the world.
