Firstly let me say that I cannot compete with Blue Tyson's in depth review of the Red covered edition. As I have only purchased the blue covered book 1, I can only comment on that so here goes,...
Short stories - you either love them or hate them. I must admit that I am surprised that a book by an author with such a legion of fans hasn't had more reviews, even allowing for the confusing number of editions out there. Still, if you are a fan, you know that GRRM has turned his hand to many genres in the past, and that is exemplified in his shorter fiction. To be fair, his early published work is a bit clunky, but it is interesting to see how he has developed, and his between section summaries and biography are more interesting than I might have expected. If you had asked me if I had read any of GRRM's short stories before getting this book I would have said "No", but on reading some of these, for example "A song for Lya" I realise that I must have done because they appeared in the various SF magazines that were ubiquitous in the late seventies/early 80's such as Omni and Isaac Asimov's Science Fiction Magazine - which are sadly now either defunct or incredibly difficult to get hold of. So all in all an eclectic and interesting collection well worth devouring in one hit or dipping into between other books.
