The first book you "oooooh"'ed about?

[Nominus Experse]

I used to read The Phantom Tollbooth at least once a week when I was around 6 years old.

And then I obsessed over The Hobbit, leading me to both read and watch the animated movie countless times.

A Wrinkle in Time series was another stint of ungodly reading.

And then I discovered the Redwall series at around age 10... It was like reading the same book over and over again, only with different characters. Such a formula was perfect for such a redundant freak as I.

Probably the first Harry Potter book. I was in a trance for days while reading it back in the day. I don't exactly remember how old I was, but I couldn't have been more than 9 or 10. I don't know.. when was the first Harry Potter book released?
