The New York Times best seller.

There are a few unbreakable rules in the game.

Stay collected. Compartmentalize. Think your next move through.

Never let your heart dictate your tactics.

The heart is impulsive.

The heart makes bad decisions.

The heart doesn’t see the long game.

The heart may have decided to get Adam back, but when the endgame comes, the heart’s going to be the one to break.
