A terrifyingly twisty, wholly original thriller following a group of amusement park visitors who get stuck on a roller coaster high above the ground―with no way down.
Six hundred and fifty feet in the air, no one can hear you scream.
Some might say that thirtysomething Cady Ellison landed herself a strange creative career, but Cady finally feels like she’s found her footing. Now an online theme park influencer, she is invited to the opening of a brand-new park by her old friend, Danny, who wants to use her online profile to help build buzz for its flagship ride, Hysteria, a record-breaking 650 foot-tall roller coaster.
When she arrives at the half-complete theme park site in the middle of the desert, Cady is unexpectedly met with her old college friend group: Femi, an award-winning actor, Naseem, a decorated novelist, and Winston, a member of a popular rock group. Wanting them all to sing the praises of Hysteria online, Danny has arranged an exclusive private ride for them, capped off with the stunning desert sunset. But when their coaster cars get to the top of the first hill, the ride stalls 650 feet above ground. With no one due on site for days and over 100-degree heat awaiting them once the sun rises, the four friends soon realize that they must unravel the secrets from their complicated past if they are to find their way to safety.

‘How to Kill With Kindness has an understated menace that simmers all the way through the book making it an absorbing read. S R Masters has drawn up an idyllic slice of village life that may not be so idyllic after all and I loved every menacing page’ James Delargy, author of Into the Flames
