An explosion rips through New York City's Grand Central Station one morning, destroying the train Karen Friedman's husband, a successful hedge fund manager, is riding in to work. Days later, with many bodies still unidentifiable, Karen resigns herself to the awful truth: her husband of eighteen years is dead.

On that same day, a suspicious hit-and-run accident leaves a young man dead in Karen's hometown of Greenwich, Connecticut. Ty Hauck, a detective, becomes emotionally caught up in the case and finds a clue that shockingly connects the two seemingly unrelated events.

Months later, two men show up at Karen's home digging into Charles's business dealings. Hundreds of millions of dollars are missing—and the trail points squarely to Charles. With doubt suddenly cast on everything she has ever known, Karen, with Hauck, steps into a widening storm of hedge fund losses, international scams, and murder. And as the investigations converge, these two strangers touched by tragedy are pulled into a deepening relationship and unwittingly open the door to a twisted—and deadly—conspiracy.

With its breakneck pacing, plentiful twists, compelling characters, and abundant heart, The Dark Tide confirms Andrew Gross's place as a master storyteller at the top of his game.
