Margaret is not producing any new Blake's 7 zines, but will continue selling the ones that she has in hand until she runs out of stock. Your best bet is to write to her and see what she still has in stock. An SAE would be appreciated, with two IRCs if you live overseas.
All Margaret's zines are A5 digest size but have full size text unlike most other British digest zines. They are stapled at the side of the spine (instead of in the middle of a folder A4 sheet). The artwork is usually pretty poor.
Zines :-
Instant review by Judith Proctor. I've read half a dozen or so issues of Rebel. It's not an expensive zine, but the contents aren't up to much. I really loathe the font and I've found a very low count of stories that I reckon to be worth re-reading. There's the occasional good one, but they are few and far between.
Adult/Slash Issue 1 contains - Shangri-La Love, A Passage Through Time, Part One (Elizabeth Everett; A/ocf)
