the book i've read the most times (and that looks like it's gonna fall apart soon) is Blue Castle by L.M.Montgomery. i can't say that it's my favourite book but it's my 'go to' book - reminds me that the happiness can be found in the simple things in life and.. just living :)
but yeah, Harry Potter is close second ;D
i'll check out ur stories when i have a bit time! they look interesting.. and i've always enjoyed short stories!
