Standard Robin Cook
If you enjoy Robin Cook's medical mystery/moral dilemma style you will probably enjoy this book, as it definitely follows his standard formant.
In this case, our protagonist Charles, a cancer researcher, is appalled to discover that the local plant is spilling hazardous waste into the river near his home and his daughter, Michelle, has contracted Leukemia. Can his research help save her in time? (you get to read it yourself to find out)
