People disappear when they most want to be seen. Jess Walker has come to a concrete campus under the flat grey 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--Alec, a courageous South African journalist with a nihilistic streak; Georgie, a seductive, pill-popping aristocrat; and Nick, a handsome geologist with layers of his own. But when tragedy strikes the group, Jess turns to Lorna. Together, the two seek refuge on a remote Italian island, where Jess tastes the life she's long dreamed of--and uncovers a shocking secret that will challenge everything she's learned.
