It's a Long Way To Dearest Gravesfield

Camila, Luz, Amity, Hunter, Gus, and Willow return to the Boiling Isles to find things are a bit messy. Raine, Darius, Eberwolf, search for ways to defeat the Collector while also trying to identify the people spreading rumours that the Day of Unity was a benevolent spell gone wrong. Eda, Lilith, Steve, and Hooty try to pick up the pieces of their lives and find a way to bring King home.

When Camila and the teenagers reveal that Belos is, unfortunately, not dead, the mission shifts and it's all-hands-on-deck to figure out where he's hiding, what his next move is, and if they can get to him before he decides to strike. In the process, Hunter has to grapple with who (and what) he is and his friends are determined to help him reach his goals of learning magic, attending Hexside, and coping with not only the death of his beloved Flapjack, but all the traumatic events he's endured (including, but not limited to, near death experiences, being raised in relative isolation by Belos, and watching the only parental figure he had for most of his life splatted on a wall).

Through it all, they build their family, help Hunter learn he can choose his own future, and discover how lucky they are to have found one another.
