From the New York Times bestselling author of The Nanny and What She Knew comes the terrifying story of what can happen after all your dreams come true.

"A standout psychological thriller...Ms. Macmillan skillfully keeps all her story's plates spinning in the air until they come crashing down in a smashing finale." -- Wall Street Journal

Be careful what you wish for...

Childhood sweethearts Nicole and Tom are a normal, loving couple--until a massive lottery win changes their lives overnight.

Soon they've moved into a custom-built state-of-the-art Glass Barn on the stunning grounds of Lancaut Manor in Gloucestershire. They have fancy cars, expensive hobbies, and an exclusive lifestyle they never could have imagined.

But this dream world quickly turns into a nightmare when Tom is found dead in the swimming pool. Was Tom's death a tragic accident, or was it something worse?

Nicole is devastated. Tom was her rock. And their beautiful barn --with all its smart features that never seem to work for her--is beginning to feel very lonely. But she's not entirely by herself out there in the country. There's a nice young couple who live in the Manor itself along with their middle-aged housekeeper who has the Coach House. And an old friend of Tom's from school has turned up to help her get through her grief.

But big money can bring big problems and big threats. And is Nicole's life in danger as well?

Nicole's beginning to feel like a little fish in a big glass bowl.

Surrounded by piranhas.

With breathtaking twists and turns and brilliant plotting, The Manor House proves once again that Gilly Macmillan belongs in a class of her own.
