I grew up around his novels but I don't think I picked them up until I watched the C4 cartoon series of Wyrd Sisters, I got interested and I brought it to read it. I ABSOLUTELY loved it, I was sixteen at the time. Since then I was hooked.
I have to buy them in HARDBACK now almost as soon as they come out, and CANNOT wait for the next Adult DW, though the arrival of the fourth Tiffany Aching novel can't come fast enough for me!
But due to his condition we have to be patient, and as long he can still write then I am happy, sad will be the day when he does stop writing.
