People disappear when they most want to be seen.

Jess Walker has come to a concrete campus under the flat gray skies of East Anglia for one reason: to be taught by the mesmerizing and rebellious Dr. Lorna Clay, whose seminars soon transform Jess's thinking on life, love, and Agatha Christie. Swept up in Lorna's thrall, Jess falls in with a tightly knit group of rule-breakers--until the dynamic among the friends begins to darken. When a tragedy shatters their friendships and love affairs and reveals a terrible secret, Jess must face the question she fears most: What is the true cost of an extraordinary life?
