a measure of relatedness between two antigenic substances
Odd Thomas is a 20-year-old fry cook who sees dead people... ghosts with unfinished business that he sometimes helps. He can also sense evil and pretty much knows when people are going to die. When a stranger he calls "Fungus Man" shows up in town, Odd has about 24 hours to figure out what’s going to happen and how the mystery man is involved. This was my first Dean Koontz book, and pretty good as horror stories go. Parts of it were truly creepy.
