"Sadly poor research.."
The book itself was interesting and somewhat entertaining. However, the whole story revolves around not being sure who fathered who, and that is evident from the very beginning.
In the final chapter, as expected, the truth is revealed...
But the assumption that the genetic test needed to prove parenthood is done using sperm rather than a simple skin sample, saliva, blood, or even hair, made me pretty depressed.
Spoiler:
Who on earth would hire a hooker to have sex with a guy to collect his sperm in a condom for genetic testing when the saliva on a glass will do the trick??
Made me think the whole book was a great deal less worthwhile when part of the story is based on a misconception that could so easily have been avoided-
