"Razor's Edge" is the title of the third book in Dale Brown's "Dreamland" series of novels, is written by Dale Brown and Jim Defelice, and was first published in 2003.
When a number of American aircraft are shot down in the skies of Iraq, the members of the advanced weapons research facility known as Dreamland are dispatched to investigate. Fears that the Iraqis have developed a deadly laser weapon are raised when it is determined that no conventional weapon could have hit the aircraft so easily.
Under direct orders from the President, the members of Dreamland must use their own experimental weapons systems to track down and destroy this new weapon, before it can cause further mayhem in the skies.
