The life of Henrietta Achilles is about to change. After years of living as an orphan, she receives a summons to the strange town of Malrenard. To her surprise, she's the only living relative of Ornun Zol--a notorious wizard, now deceased, who leaves Henrietta with his house and everything in it.

With Ornun Zol gone, escaped creatures and misfired curses have been spilling out into Malrenard. If that's not enough, Henrietta will discover countless squabbling squatters inside her uncle's abode: soldiers, bandits, tiny monsters, and more. Then there's the matter of the strange black cat following Henrietta around . . .
