The Dragon Factory

Joe Ledger works for the Department of Military Sciences (DMS), a secret government unit. His new enemies are two rival groups of geneticists, each with its own plan for remaking the world through engineered biology.

One group builds exotic transgenic monsters and genetically enhanced mercenary armies. The other uses modern technology to carry on the Nazi Master Race program begun by Josef Mengele. The two groups compete, but they agree on one point: the DMS has to be destroyed.

They do not wait to be found. They strike first, and Ledger and his unit are on the defensive from the opening stretch.

This is the second Joe Ledger novel, after Patient Zero. Echo Team, Mr. Church, Rudy Sanchez and Major Grace Courtland all return. The threat is different this time, since zombies give way to engineered biology and the people who would use it.

The book is a fast, violent thriller with horror and science fiction elements. It continues the series, though it can be read largely on its own. The question that drives it is whether the DMS can survive an attack from two directions at once.
