Yesterday we learned the terrible news that our dear friend Maureen Kincaid Speller had passed away. Maureen was diagnosed with cancer back in March, but she had made remarkable progress and at the beginning of the summer her prognosis looked a great deal better. Her death on Sunday came as a bitter blow. Death is always difficult to come to terms with, but in the case of Maureen it seems doubly so. She had so much more still to give. Her indomitable spirit, her keen intellect, her wicked sense of humour and the all round pleasure in being in her company – these things make her loss all the more painful. I don’t think I will ever get used to the knowledge that she is no longer with us.

I will value in particular the memories of our many discussions of science fiction – its definition and relevance, its unique contribution to literature, the state of the field. So much laughter and so much passion. I was delighted when Maureen was made senior reviews editor at Strange Horizons, because I knew how much she would relish this challenge and how much support and experience she could offer to newer writers. I will treasure especially the time we spent together immersed in the Shadow Clarke through most of 2017. Maureen wrote some excellent criticism – because of course she did – but there was also all the stuff behind the scenes, the free exchange of ideas and opinions, the joy in thinking.

Maureen’s work as a critic and commentator has been a lifelong commitment and I will have more to say about that in the coming months. For now, I just want to say Maureen, your loss to us is incalculable. We love you with all our hearts, and will miss you forever. Our sincerest condolences to Paul, Maureen’s beloved husband, and our beloved friend. Our thoughts are with you.
