The brand new hilarious, emotional and thought-provoking book club read about twin sisters who make a bet to switch lives for a week, for fans of David Nicholls, Sophie Kinsella and Cecelia Ahern.

Two sisters. One Bet.

And a lifetime of secrets uncovered…

Morning TV’s favourite twin sisters, Alice and Edie, may share the screen, but that’s where their similarities end. Their viewpoints are far from identical, and whilst their on-air clashes keep viewers hooked, off-camera, their relationship is far from picture-perfect.

After a heated argument on live television threatens their jobs, the fiery duo make a bet: neither could last a week in the other’s shoes. Determined to prove each other wrong, they secretly swap lives — without telling a soul.

What starts as a battle of wills quickly spirals into chaos, as each sister discovers that the other's life is far more complicated than it seems. Between dodging awkward work situations, marital issues, and meddling in each other’s families, Alice and Edie’s rivalry turns from a competitive bet into an opportunity to help change each other’s lives for the better.

But will their relationship survive?
