Death Echo

When she joined St. Kilda's, the elite security consulting firm, Emma Cross thought she'd left behind the blood, the guilt, and the tribal wars that defined her life at the CIA. Yet, trading spying for investigating yacht thefts didn't alleviate the danger -- or melt away her professional paranoia. Now, the same good instincts that got her into trouble at the agency might be what will help her survive her latest case.With some arm-twisting, St. Kilda and Emma are tracking a yacht named Blackbird, a dead ringer for another ship that went missing somewhere between Vladivostok and Portland a year earlier. Emma knows the boat's intended cargo is lethal. What she needs to find out is whether it's biological, chemical, or fissionable. And she's only got seven days to uncover the truth . . . or a major American city will be lost.
