Rivalries and resentments between mums and non-mums spiral wildly out of control in the compelling new book by the bestselling author of The Fifth Letter

"Super addictive, cleverly plotted and ridiculously relatable ... This is definitely one of those books where the characters begin to feel like your new best friends within the first few chapters" Booktopia

An online rivalry between mums and non-mums spills dangerously into the real world

Poppy's world has tipped sideways: the husband who never wanted children has betrayed her with her broody best friend.

At least Annalise is on her side. Poppy's new friend is determined to celebrate their freedom from kids so together they create a Facebook group to meet up with like-minded women, and perhaps vent a little about smug mums and their privileges at work.

Meanwhile Frankie would love a night out, away from her darlings - she's not had one in years - and she's sick of being judged by women at the office and stay-at-home mums.

When Poppy and Annalise's group takes off and frustrated members start confronting mums like Frankie in the real world. Cafes become battlegrounds, playgrounds become warzones and offices have never been so divided.

A rivalry that was once harmless fun is spiralling out of control. Because one of their members is a wolf in sheep's clothing. And she has an agenda of her own.

"Super addictive, cleverly plotted and ridiculously relatable...thoughtful, whip-smart and emotionally rich contemporary fiction" 9Honey
