From the New York Times bestselling author of The Blue Zone comes this second mesmerizing thriller about a woman who must unravel the secrets from her dead husband's past.

An explosion rips through New York City's Grand Central Station, destroying the train Karen Friedman's husband, a successful hedge fund manager, is riding in to work. On the same day, there's a suspicious hit-and-run accident in Karen's hometown of Greenwich, Connecticut, and Ty Hauck, a detective, finds a clue that shockingly connects the two seemingly unrelated events.

Months later, two men show up at Karen's home digging into Charles' business dealings. Hundreds of millions of dollars are missing--and the trail points squarely to Charles. Suddenly Karen, with Hauck, steps into a widening storm of hedge fund losses, international scams and murder. And as the investigations converge, these two strangers are pulled into a twisted--and deadly--conspiracy. With its breakneck pacing, plentiful twists, compelling characters, and abundant heart, The Dark Tide confirms Andrew Gross' place as a master storyteller at the top of his game.
