'Keeps us guessing until the very last page' Liz Nugent
'Intense psychological thrillers that explore emotional danger with relentless, surgical accuracy' Tana French
'Like Gone Girl . . . the most gripping thing I've read for ages' Evening Standard
'This brilliant binge-read thriller has a real roller coaster of an ending' Heat
Keep your friends close. And your enemies closer.
Cara shouldn't have survived the attack. But at the last moment, a stranger snatched her to safety.
In the hours that followed, she told her Good Samaritan secrets she'd never told a soul.
Not even her husband. Especially not her husband.
In the aftermath, Cara is home, healed and safe. Which is when the anonymous threats begin.
Someone knows things about her that they shouldn't.
Cara's Good Samaritan offers to help - to save her all over again.
That night, Cara made a friend for life. But what if she isn't a friend at all?
