Thanks all for the suggestions. I did think it sounded like Blood Music... which I started reading once, but never really got into. But I'm convinced --or as convinced as anyone can be about memories from a while back-- that what I'm barely remembering was a short story. So the fact that Blood Music was derived from what was originally a short story sounds promising. Some other interesting suggestions too. I think I can feel a dive down a literary rabbit hole coming on! EDIT: Having followed up some of the leads provided here, the basic premise of Blood Music does sound like what I'm trying to remember. But I'm convinced the story I'm after was less 'expansive' [for want of a better word] and just centred around this one guy, gradually warping & merging into the fabric of his home. It would be interesting to find the original short story and see if it was like this and then got hit by the "We need more sharks and explosions!" stick, when being re-worked into a novel.
