Mildew is a young cat who lives in the Irish seaside village of Everdusk, where, as the name suggests, it is always dusk — which makes things pretty spooky.
Mildew is wildly curious or easily distracted depending on who you talk to. As assistant to ancient hedge witch, Goody Dunbar, Mildew is sent out into the village of Everdusk on many a witchy errand. But sooner rather than later, Mildew’s curiosity (er, distractedness?) takes charge, the errand falls by the wayside and Mildew… well, in a place like Everdusk and with a cat like Mildew, you never quite know what adventure (er, trouble?) this curious kitty might get into.
