An eerily gorgeous girl can sing out their bit beasts along with their souls, and nothing they do will stop it. Kai will have to resort to the real skills the Abbey had been teaching him--that of an assassin, in order to save, not only his teammates, but himself.

Kai should have burned to death. Somehow, he wasn't, but Dranzer has vanished, his body is going through some sickly changes, and Max has jumped overboard and vanished into the depths of the sea. Ayah's song has done more to Kai and Max than just given them a power boost to survive Cain, and no one knows what, why, or whether they will live through it. Sequel to "Before Beasts, There Was Wind"

Everyone on the team is taken with Ayah--except Kai. No way is he about to let his guard down to the inhuman girl who had just stolen their souls, no matter her good intentions or her unearthly beauty. But he has bigger fish to fry. After all, he had just unleashed his assassin's blade on the world, and someone from Biovolt has noticed...and isn't pleased. Sequel to "Before Beasts, There Was Sound"

Their pirated ship sunk, land finally found, Kai and his transformed team find themselves out of the pan and into the fire when they're captured by the U.S. Army, who have commandeered Max's Mom's research about their bizarre combination with their bitbeasts and intend to finish it themselves, with little thought to the humanity of their subjects. Summary of previous books inside.

The Bladebreakers must cross Russian tundra, warring countries, and stormy seas to reach a nuclear war-ravaged Japan, where hopefully salvation will be found in Kenny and his bit beast Dizzira.

Recovering from being blown out of the sky by a missile, Kai and the transformed Bladebreakers head out for the frozen tundra of Alaska to find the lonely Tala, who is hunted down for his connection to the Abbey assassins. But he isn't the only one waiting for them in the frozen land. Summary of previous books inside.

Tala has been pulled out from the frozen tundra and now his frozen cocoon is the only thing stopping their stolen ship from sinking. Once he wakes up, the ice will melt, and they will be plunged to the bottom of the Arctic Ocean. With Max severely injured, Ayah spent, and the rest of the team exhausted, their fate may be left to Ayah's emaciated brother of light. Who hates them.

Just before Tala moves in with Kai, he sends a warning to flee. The leftovers of Cain's plan is about to plunge Japan into nuclear warfare. That's easier said than done when you and the girl you love have huge, useless wings and are essentially hunted, bit-beast creating aliens. Life was so much easier when all he had to worry about was his past as a Beyblade assassin. (Summary of previous books inside)

Tyson and Dragoon have combined at the wrong time, namely on a ship full of hunters out to keep the Bladebreakers as their test subjects until they're usefulness is spent. A typhoon ensues and swallows the crew, peaceful waters aren't promised, the US military has them in their sights, and there is still no sign of Max, Ray, or salvation in sight. Summary of previous books inside.

Kai is burnt by Dranzer, which is a first. If that was the only strange thing he could handle it, but then he is kidnapped by his old Biovolt assassin's ring just to find someone new has taken over, someone who isn't entirely human. Now a monster seeks to use Kai's killing beyblade to clear the earth for his species, and if Kai doesn't cooperate, the Bladebreakers will be killed. Sequel to "Before Beasts, There Was Fire"
