Two women, two dark secrets. Do people ever really change?

How well do you really know your friends?

Frances Metcalfe is struggling to stay afloat. A stay-at-home mum whose troubled son is her full-time job, she thought that the day he got accepted into the elite Forrester Academy would be the day she started living her life. Overweight, insecure and lonely, she is desperate to fit into Forrester’s world. But after a disturbing incident at the school leads the other children and their families to ostracise the Metcalfes, she feels more alone than ever before.

Until she meets Kate Randolph.

Kate is everything Frances is not: beautiful, wealthy, powerful, and confident. And for some reason, she's not interested in being friends with any of the other mums – only Frances. As the two bond over their disdain of the Forrester snobs and the fierce love they have for their sons, a startling secret threatens to tear them apart...because one of these women is not who she seems.

Her real name is Amber Kunik.

And she's a murderer. A chilling web of lies, deceit and betrayal, from the bestselling author of The Party.
