Random Hearts — Warren Adler

What the author of The War of the Roses did for hate, he now does for love.

He's a happily married man. She's a happily married woman with a little boy and a good life. Or so they both believe. There's absolutely no reason why they should ever meet.

Until a commercial airliner crashes into the Potomac River. Two of the victims are linked by a clue that at first stuns and baffles, then draws together their surviving spouses.

The explosive discovery leads them on a journey that forces them to confront the mysterious and random nature of love--and the transforming power it wields over men and women caught in its relentless maelstrom.
