The Infinity Plague (Biowarriors, Book 1)

Plot

"At the end of the 21st century, the techniques of genocide have become a science. The only safeguard to Earth's uneasy peace is a vast stockpile of genetically engineered biological weaponry--weaponry so devastating and uncontrollable that the only alternative to peace is swift and mutual annihilation... Such a course seems unthinkable to Dr. Jerome Walden, head of the North American Alliance biowarfare engineering team. But when the research planet Delta Cygnus 4 becomes the site of first contact wit the Frinn--an alien race seemingly bent on the destruction of all humankind--Walden must face the consequences as the most devastating weapon of all is unleashed."--Pg. [4] of cover.
