The one book I do read right around Halloween is The House with a Clock in its Walls by John Bellairs. It's the first in a series of books about Lewis Barnavelt. If you haven't read it, here's a sysnopsis from Goodreads:
"Lewis always dreamed of living in an old house full of secret passageways, hidden rooms, and big marble fireplaces. And suddenly, after the death of his parents, he finds himself in just such a mansion--his Uncle Jonathan's. When he discovers that his big friendly uncle is also a wizard, Lewis has a hard time keeping himself from jumping up and down in his seat. Unfortunately, what Lewis doesn't bank on is the fact that the previous owner of the mansion was also a wizard--but an evil one who has placed a tick-tocking clock somewhere in the bowels of the house, marking off the minutes until the end of the world. And when Lewis accidentally awakens the dead on Halloween night, the clock only ticks louder and faster. Doomsday draws near--unless Lewis can stop the clock."
Yes, it is a book for elementary aged children but, a good book is a good book! I love the characters, especially Rose Rita Pottinger and I really want a neighbor just like Mrs. Zimmerman. The second book in the series is The Figure in the Shadows, followed by The Letter, the Witch and the Ring which I've yet to read as it's really hard to find...I might have to go over to Amazon for a splurge for a Halloween treat....
Please let me know what you like to read during Halloween so I can grow my list and share with everyone.
