Her Every Fear by Peter Swanson

Hoping that time away will help her overcome the past trauma of her life, Kate Priddy agrees to swap apartments with her cousin Corbin Dell. But when she arrives in Boston, Kate discovers that Corbin's neighbour has been murdered--and the police suspect her cousin is the murderer. Corbin calms her nerves, and she believes him until she comes across disturbing objects in his apartment. Jet-lagged and emotionally fragile, Kate can barely trust herself, let alone strangers she's just met. Yet the danger Kate imagines isn't nearly as twisted as what's about to happen. When her every fear becomes very real.
   And much, much closer than she thinks.
   Her Every Fear is a scintillating novel that displays Peter Swanson's insight into the darkest corners of the human psyche and his virtuosic skill for plotting that have propelled him to the highest ranks of suspense, in the tradition of such greats as Gillian Flynn and Paula Hawkins.
