Aside from sales, the letters from readers have been primarily positive.

I have been a reader of Science Fiction and Fantasy for a long time, since I was 11 or 12 I think, so I understand it and I'm not at all surprised that readers of the genre might enjoy my books.

Of the two, I would think of my work as closer to Science Fiction than Fantasy.

Science Fiction is not just about the future of space ships travelling to other planets, it is fiction based on science and I am using science as my basis for my fiction, but it's the science of prehistory - palaeontology and archaeology - rather than astronomy or physics.

I have heard Science Fiction and Fantasy referred to as the fiction of ideas, and I like that definition, but it's the mainstream public that chooses my books for the most part.
