An insane Shifter stole Rysa's talisman, jacked her body, and caused her abilities to nova. Now, she wastes away in front of Ladon's eyes and he can't stop the power that's eating her alive.

Watching her anguish triggers flashbacks. When Ladon's soul ruptures, only Rysa can give him the cure he needs, but she's too far away to stop what's eating him alive.

With the help of the newly-healed, newly-invincible Derek, Rysa runs from the worst Fates and Burners on the planet as she desperately tries to heal Ladon—and herself. Can she solve their problems—and recover her talisman—before the most powerful Fate on Earth destroys everything and everyone they hold dear?

Enter the explosive, genre-bending World on Fire universe where Science Fiction meets Urban Fantasy: Dragons, immortal warriors, family, love… and unknown science so advanced it's indistinguishable from magic.
