Query: Greatest? Maybe!

This book is defenitly one of the greatest fantasy-books ever. Stephen Donaldson surely takes me to a world which I never want to leave. But the greatest thing probably is the way in which he describes people. Thomas Covenant of course is one of the most wonderful charaters I've ever met. Because you really meet them in this book. Don't ever stop writing Stephen!
