Ghosts of Greenglass House, by Kate Milford, was published in 2017 by Clarion. It is the sequel to Greenglass House.
Milo keeps waiting for that special relief that usually settles in at the start of winter vacation. But it’s not coming. For one thing, there’s no snow, and it’s hard to get into the spirit when all you have to work with is a crust of stupid frost. For another, it’s been a tough couple of weeks at school, thanks to a teacher who doesn’t get how much Milo hates having attention called to him, and to his adoption. Then there’s the lone guest staying at his family’s inn, an art student who seems determined not to leave until he’s sketched very single stained-glass window in the place. Worst of all, Milo’s friend Meddy has been conspicuously absent for a long, long time. It’s almost enough to make him wish for a winter break like last year’s, when his house was full of secretive guests and unexpected mysterious, and Meddy had helped him unravel it all. There’s no chance of that happening again, though; Milo is certain of it. Until the bell rings.
