Meh. It's a slightly above-average book. The trademark Lemony Snicket wit is here, and it makes the book much more fun. As a whole, though, it feels forgettable and pretty mediocre. There are some colorful characters, as you will typically find in a Snicket book, and I can see them growing weirder and more interesting in the next few books.
I've heard the next book is better, I'll give it a shot.
