I knew a girl who had re-read the PJO series 27 times...

I've read PJO (pre-HoO) three times.

And then with HoO every book I've re-read the the TOTAL series (PJO+HoO) three times and after I get a new HoO book I read it in a day and then eventually re-read it slowly.

Why you may ask?

Wiki. If you don't read the book fast enough spoilers. e.e

So at least six, lol.
