A woman's birthday party takes a dark turn in a poignant, heart-stopping new novel from the reigning queen of suspense, NYT and USA Today bestselling author of Behind Closed Doors, The Breakdown, and Bring Me Back.

"A heartbreaking page-turner that will have you up at night reading just one more chapter." --Catherine Steadman, #1 New York Times bestselling author of Something in the Water

"The phenomenal B. A. Paris has done it again! I devoured The Dilemma in one sitting--it grabbed me from the very first page and wouldn't let go until I'd finished. Secrets, guilt, shame and heartbreak--this story has it all in spades."--Sandie Jones, New York Times bestselling author of The Other Woman

Knowing the truth will destroy her. Keeping it secret will destroy him.

It's Livia's 40th birthday, and her husband Adam is throwing her the party of a lifetime to make up for the wedding they never had. Everyone she loves will be there, except her daughter Marnie, who's studying abroad.

But although Livia loves Marnie, she's secretly glad she won't be there. Livia has recently uncovered a secret about their daughter which, if revealed, will shake the foundation of their family to its core. She needs to tell Adam, but she's waiting until the party is over so they can have this last happy time together.

Adam, meanwhile, has his own surprise for his wife: he's arranged for Marnie to secretly fly back for the family celebration. But during the day, he hears some terrible news and he too is faced with a dilemma.

How far would you go to give someone you love a last few hours of happiness?
