The war with Gaia has been over for a month now. The demi-gods are settling into new life but one is considering leaving. Nico doesn't belong at camp. Or anywhere really. Too dead for camp. Too alive for the Underworld. The only thing keeping him there was a certain son of Apollo. That was until he found a strange girl who not exactly a demi-god. Will tries to be the best head doctor. But he's also trying to be friends with the son of Hades which seems to be a complete challenge. But when the new patient who Nico found seems to be a... multi halfblood, becoming Nico's friend seems to be the least important thing now. The new girl is utterly lost. Reality is upside-down. Hers and the demigods. With the help of the seven and Will and Nico, they must find out why she is there now and what wants her powers...
