"As I opened the door and stepped into the humid night, her scream followed me out. But I knew there was still love for me in her heart....

"I'm unforgettable."

Paul Strom has the perfect life: a glittering career as an advertising executive, a beautiful wife, two healthy boys, and a big house in a wealthy suburb. And he's the perfect husband: breadwinner, protector, provider. That's why he's planned a romantic weekend for his wife, Mia, at their lake house, just the two of them. And he's promised today will be the best day ever.

But as Paul and Mia drive out of the city and toward the countryside, a spike of tension begins to wedge itself between them, and doubts start to arise. How perfect is their marriage, or any marriage, really? How much do they trust each other? Is Paul the person he seems to be? And what are his secret plans for their weekend at the cottage?

Forcing us to ask ourselves just how well we know those who are closest to us, Best Day Ever crackles with dark energy, spinning ever tighter toward its shocking conclusion. In the best-selling vein of The Couple Next Door and The Dinner, Kaira Rouda weaves a gripping, tautly suspenseful tale of deception and betrayal dark enough to destroy a marriage...or a life.
