How far would you go to protect your perfect life?

Marianne has a life others dream of. A beautiful townhouse on the best street in the neighbourhood. Three bright children who are her pride and joy.

Sometimes her past still hurts: losing her mother early, growing up in foster care. But her husband, Simon, is always there. A successful surgeon, he’s the envy of every woman they’ve ever met. Flowers, gifts, trips to France: nothing is too good for his family.

Then Simon says another woman’s name. The way he lingers on it, Caroline , gives Marianne a shudder of suspicion, but she knows it’s nothing – she can’t entertain this flash of paranoia.

In the old days, she’d have distracted herself by excelling at work, but Marianne left her glamorous career when she married. She’d speak to a friend, but she’s too busy with her children and besides, Simon doesn’t approve of the few she has left.

It’s almost by accident that Marianne starts to learn more about Caroline. But once started, she can’t stop, because what she finds makes her wonder: is the question she should be asking not ‘should she be jealous’, but... ‘should she be scared?’

Fans of The Girl on the Train and I Let You Go, who are looking for a dark, gripping psychological thriller with a final twist to put their jaw on the floor, will love Our Little Lies.
