Chimera Island. For more than a century, the tiny atoll has been the subject of legend and rumors. Mysterious sightings. Strange deaths. Unexplained disappearances.

A transport plane sent to Chimera to evacuate frightened scientists from a climate research station on the island disappears, along with a Chinese spy ship prowling nearby waters. The U.S. Coast Guard sends its most secret team to investigate, Deployable Specialized Force-P—the P is said to stand for phenomenon.

DSF-Papa, led by Lieutenant Commander Douglas Munro Gates, discovers there is more to the legend of Chimera Island than rumors and folklore. The climate research station is wrecked. Strange creatures skulk through the jungle overgrowth. And reality may not be as it seems. Worse, someone - or something - is determined to stop the Coasties from discovering the truth about the island.

With evacuation impossible, DSF-Papa must discover the secret of Chimera Island or become part of its legend.
