Philosophy professor Neil Weber can't think of one good reason to get up in the morning. His wife has left him, his academic research has sputtered, and the prospect of tenure is more remote than ever.

Until Lucia Vanotti disappears.

A college student at Neil's Southern university, Lucia has a secret of her own--one that haunts her relationships and leads to reckless, destructive behavior. When Neil is drawn into the mystery of her disappearance, he finds new energy, purpose, and relevance. But at what cost? Each clue pulls him deeper into Lucia' s dark past, but also into the hidden lives of his closest friends and colleagues.

What has driven Lucia to risk everything? And why does Neil, a professor who hardly knew her, care so deeply about finding her? From campus classrooms to sex dens to backwoods hideaways, The Department reveals the world through the dual perspectives of Lucia and Neil as they descend into obsession, delusion, and the dangerous terrain of memory--uncovering the traumas that drive them to behave in ways they never could have predicted or imagined.

Perfect for fans of Jessica Knoll, Ruth Ware, and Gillian Flynn
