What city is west marin middle school in on the book called genius files?

The city where West Marin Middle School is located in the book "The Genius Files" is not explicitly stated. However, the story takes place in California. This is inferred through various clues like the setting being near the Pacific Ocean, and the character's frequent mention of California beaches.

The book also mentions the school being near a town called "Harbortown," which, unfortunately, is not a real place in California. It's likely a fictional town created for the story.

Therefore, while the exact city remains unknown, it's safe to assume that West Marin Middle School is located in a coastal town in California.
