Obssessed With Harry Potter discussion

Hi everyone, so I'm kind of an outsider here because I'm not "obsessed" with Harry Potter (yet?). I just finished Harry Potter and the Chamber of Secrets, since I decided a month ago to read all of them (yes, I haven't read any of them, a shame I know). I found the first two enjoyable but I'm not that hooked on them yet so I was wondering, what book in the series was the one that "did it" for you ?

The first. I just couldn't put it down. And so it continued from there.

It was initially the first, but the prisoner of Azkaban was the one that got me hooked.

The Prisonder of Azkaban for me too. Once you read it you won't look back.
