Contagious

Alien invaders threaten humanity in Sigler's over-the-top thriller, the sequel to Infected. In the near future, U.S. president John Gutierrez goes straight from his inauguration to crisis management when his national security team informs him that he must focus his attention on Project Tangram, a secret government program to stave off an epidemic caused by alien parasites, which form itchy blue triangular patches on the skin. Victims eventually become paranoid and violent. As the infestation spreads, Gutierrez must decide whether the outbreak can be contained without the use of tactical nukes on American soil. Meanwhile, the creatures responsible for the parasites get a foothold in Michigan through a seven-year-old girl, who manifests possession by drawing blue triangles on her dolls. While lacking the psychological sophistication of Jack Finney's The Body Snatchers or David Gerrold's War Against the Chtorr series, this page-turner builds inexorably to an explosive ending.
