Dead. That's what all the students at Underworld Academy were. Dead, invited to Hades's academy, gaining ranks, and having "another chance at life". That was what Regina Hollows went through when she died, and was wrongly sent to Asphodel. Everyone has high hopes for Regina, but when she is ranked the lowest, she must climb her way back up. Then, several students fall under the Curse of Calypso and are lost to the Thorn Cavern. Regina must figure out how to get the Cure, so that they can save the students before they are lost forever.
