Double Helix (2004) is a novel by American writer Nancy Werlin about 18-year-old Eli Samuels, who works for a famous molecular biologist named Dr. Quincy Wyatt.

The job is perfect, and the wages are great, but Eli can't help but notice that Dr. Wyatt seems to be a little too interested in him.

The story addresses a lot of recent scientific breakthroughs, and uses them as plot devices.

Scientific American recently published an article detailing the possible uses for the information gathered from the Human Genome Project.

Modern advancements in gene studies currently can detect and, in some cases, even predict the presence of a genetic abnormality.
