Lost Child takes a small but definite step back in quality from the first book, with our three witches facing off against a new supernatural threat, but mostly their own indecision and confusion. Autumn has brought Judith on as an employee, and Autumn is Judith's proper apprentice, but the relationships are much the same. A small child is haunting Lizzie, not a ghost but a premonition of a future horror. And everybody is too wrapped up in Christmas business to notice that Eldritch Horrors from Beyond Space and Time are planning a horrible ritual to destroy the town and take its supernatural nexus.

While villainous, compared to the first book the foes are little generic, and we already know the parameters.
