I am sure that it was just another early example of what came to be called a fantasy heartbreaker I can assure this is not the case.Bifrost is A-M-A-Z-I-N-G.It took me a lot of time and it was a real pain in the neck but after some years i was able to get copies of the first and the third volume, i read them some time ago and i was struck, particularly by the Magic system.
