The Parasite, a science fiction novella (40,000 words) by Neal Asher.

After mining complex ices deep in the Solar System, Jack Smith is concerned about his profit margin, but is it him who doesn’t want to face quarantine or something squirming inside him? The Cryon Corporation Director, Geoffry Haven, is also concerned about the bottom line and might consider Jack an expense he can no longer afford, though perhaps suitable for a starring role in a snuff movie. Meanwhile, the human and unhuman agents of World Health must investigate. Perhaps it’s time to deploy vat-grown killers and an anti-photon weapon, because the parasite is coming to Earth, and it’s hungry.

The Parasite was first published by Tanjen Ltd as an illustrated novella back in 1996. Tanjen closed down a number of years later and since then the novella has been difficult if not impossible to obtain. There are copies out there, but checking recently I haven’t seen one for below $50.00, which is a hell of a lot for something only 130 pages long and perhaps only for completists. I’ve edited it again, thought I haven’t been too heavy-handed since I didn’t want to deliver something that had completely ceased to be the original. This is my first attempt at self-publishing through Amazon Kindle. I hope you all enjoy it!
