Love and other lies : a novel / Ben McPherson.

Enhanced descriptions from Syndetics:

A mother and father search for the truth behind their daughter's disappearance in this stunning psychological suspense novel that takes Nordic noir to a level that is "emotional, painful, and utterly memorable" (Alex Marwood, Edgar Award-winning author of The Poison Garden).

Cal and Elsa have the perfect relationship; they're still deeply in love after fifteen years of marriage, they have three incredible children, and most importantly, they never lie to each other. But when their oldest daughter disappears in a summer camp shooting outside Oslo, Norway, Cal and Elsa's lives are changed forever.

Cal believes his family is strong enough to weather this blow and hold out hope for Licia's return, but as they all deal with the tragedy in different ways, doubts begin to creep in. Their younger daughter, Vee, is definitely hiding something from her parents. And Elsa would never lie to Cal, but is she telling him the whole truth? As the reality of what happened at the camp comes to light, each family member's morals will be tested. In the end, will their love for one another be enough to hold them together?
