I almost didn’t read this book–the blurb on the inside jacket didn’t sound especially exciting, nor were there any reviews or recommendations on the back.  I went online to check it out first, and I saw that this book was a National Book Award Nominee, winner of the Edgar Award for Best Juvenile Mystery, Nebula/Andre Norton Award Nominee, and a New York Times bestseller.  Who knew?  I started to read and I literally couldn’t put it down.  Greenglass House is literally a green glass house–a house loaded with green stained glass.  It is located high up in the mountains and used to be a home for smugglers.  Access is difficult, especially in winter, and is by cable car.  It is currently a bed and breakfast inn, run by the Pines and their 10-year-old son, Milo.  Winter is usually a slow time, however, the week before Christmas is suddenly booming.  Five unexpected guests show up, then another, and then two old regulars. A village woman and her daughter, Meddy,  come to help Mrs. Pine take care of the guests.  With the guests come personality clashes and if that wasn’t bad enough, someone is stealing from the guests.  As the story unfolds, you learn more and more about each guest.  Each is at Greenglass House for a specific reason, not a winter vacation.    After the thefts,  Milo and Meddy play a game similar to Dungeons and Dragons in which they make up characters for themselves complete with a new name and biography.  They analyze each guest, pretending why they are there, and who could have stolen the items.  Working off of their hypotheses, they find the items and return them.  They uncover the secrets and history of the house, but also reveal a dangerous character.  The pace of the story is perfect–not too slow but fast enough to make you not want to put the book down.  This book is highly recommended for those who love a good mystery.  Plus, get a new book jacket printed to advertise how good this book actually is.
