From Rick Riordan Presents:
After reuniting with Ayanna, who is now in his world, Tristan travels up the Mississippi in pursuit of his archenemy, King Cotton. Along the way they encounter new haints who are dead set on preventing their progress north to Tristan’s hometown of Chicago. It’s going to take many Alkean friends, including the gods themselves, the black flames of the afokena gloves, and all of Tristan’s inner strength to deliver justice once and for all. Shocking twists, glorious triumphs, and a cast of unforgettable characters make this series conclusion as satisfying as it is entertaining.
