IMMUNITY

When Nick Horne, police crime scene exeminer turned science journalist, hears rumors of a leak at Helikal's genetic engineering lab in Western Australia's wheatbelt, he tries to contact geneticist David Mora for details. After learning that Mora has disappeared, Horne realizes that someone is trying to stop him investigating Helikal. He reluctantly teams up with Tom Purdy, a US defense attache with diplomatic immunity who is also looking for Mora and fears that he may have given a bioweapon to a terrorist group threatening to unleash it on America. Soon, Horne is not only fighting for his life, but must make decisions that can affect the world - but first, he has to decide who he can trust.
