I know that there are 21 other reviews and I am not going to say anything unique but I have loved this series for so long, I just want to put it in writing.
Sometimes you are just loping along in your own life and something wonderful happens - you fall in love, get your dream job, fall pregnant (if you want to be!) and for a while the world is a shing place where everything is glowing and bright. Sooner or later the shine dims, but the memory, of how happy you were, how special it was, that stays.
So here you are, loping along, wondering what book to buy next, and here it is, a shining experience waiting for you... This is the start of a magical series (ignore the awful cover drawing show here! It doesn't reflect the books at all)
I reread these books on average once every two years, so all the characters are now old and familiar friends. They are complex, with foibles and mistakes, with heroism and madness, with granduer and evil. There are dreamers and victims, great imagination and a sense of an entire universe out there.
It isn't even strictly speaking science fantasy. It's set on earth, and everything is (sort of) feasible. It's an epic tale, one to sink your teeth into. It will fill your days and invade your dreams. Enough already - go out and buy it!!
