For Chel, Tomlin, and Mathias, life is simple but good. They share a home and a love, and despite a few conflicts of personality, are happy. Mathias runs a magic shop, where he makes magic items and potions for his customers, and Tom is his familiar, helping supply his magic. Chel, who's not magical, works at a bookshop and makes sure dinner is on the table for his lovers.

When Mathias suddenly comes down with a mysterious illness, Chel and Tomlin seek out answers. As Mathias's familiar, Tomlin can sense that nothing is wrong with the magical parts of him, but when a trip to the doctor's indicates nothing is wrong with him physically either, they start to worry.

Then Mathias collapses, and the search to find the truth becomes urgent.
