A psychologist shouldn't be losing her mind, but Hannah is anyway. She needs a new job and lots of sleep—fast. Desperate for a change of fortunes, she contrives a meeting with her former classmate. As a student at Harvard, Rowan became famous on Instagram by chronicling a glamorous life.

The two women soon form an obsessive friendship, and Hannah is drawn into a privileged new world. But when a garden party takes a shocking turn, Hannah and Rowan find themselves suspected of murder. The Cambridge police start closing in, uncovering their dark secrets one by one. Now, the friends are unraveling—and by the time the truth comes out, one of them will be dead.

"Influenced is the sort of book where you end up staying up until the middle of the night because you can't let it go. Hannah is a character you fall in love with... and then stay on the edge of your seat as her life spirals out of control. A must read for psychological suspense lovers." -- New York Times and Washington Post Bestseller Mike Omer
