Summary from the publisher:
It's wintertime at Greenglass House. The creaky smuggler's inn is always quiet during this season, and 12-year-old Milo, the innkeepers' adopted son, plans to spend his holidays relaxing. But on the first icy night of vacation, out of nowhere, the guest bell rings. Then it rings again. And again. Soon Milo's home is bursting with odd, secretive guests, each one bearing a strange story that is somehow connected to the rambling old house. As objects go missing and tempers flare, Milo and Meddy, the cook's daughter, must decipher clues and untangle the web of deepening mysteries to discover the truth about Greenglass House—and themselves.
This book has everything: mystery, interesting characters, suspense, fantastic world building, and several twists and turns. I loved every minute of it. I resonated with introverted Milo and his love of holiday traditions, as well as his frustration when those hopes for traditions are dashed one after the other by each new and strange guest. The house itself is just as strange and Milford does a wonderful job of making the oddities of the house as intriguing as the characters themselves. Milo and Meddy are my new favorite partners in crime; I love their character dynamic and what each brings out in the other. The author creates a world in which the characters must uncover the truth at the price of discovering who they are and the part they have to play in their own story.
This is a great adventure to snuggle up with in the (hopefully) cooling weather. Keep an eye out for the sequel, Ghosts of Greenglass House, which releases next Tuesday, October 3.
