Calypso Down: A Chris Black Adventure Volume 4

"The perfect collision of action, intrigue, and marine science . . ." --Emma Hickerson, Aquanaut and Member of the Women Divers Hall of Fame

"Brisk and exciting." --Publishers Weekly

An undersea laboratory in a violent storm, an attack imminent. Only Chris Black can save the mission gone awry.

Indomitable marine biologist Chris Black arrives in Florida intending to assist young aquanauts on an internationally funded mission to Calypso, the new undersea laboratory deployed on the edge of a coral reef. But as online trolls jeopardize the integrity of the mission and mysterious attacks suggest that someone would prefer that Calypso never come up for air, Chris is called upon to join the underwater team. Already embattled by financial, political, and scientific skepticism, the mission goes awry when a tropical storm builds and threatens the safety of the scientists onboard. Will Chris be able to save the mission and everyone involved amidst a perfect storm?

Dr. James Lindholm dives deep for his inspiration. His novels are based on a foundation of direct, personal experience with the undersea world. He has lived underwater for multiple 10-day missions to the world's only undersea laboratory and has even found himself alone on the seafloor staring into the eyes of a hungry female great white shark. Along with his ocean adventures, Lindholm has drafted text for an executive order for the White House and has briefed members of the House and Senate on issues of marine science and policy. He works as the Chair of the Department of Marine Science at California State University, Monterey Bay. James Lindholm's diverse writing portfolio includes textbooks, peer-reviewed scientific journal articles, and the Chris Black series of action/adventure novels.
