Number One bestselling author Sophie Kinsella returns with an irresistible new standalone about family love, family tensions and exactly what you might hear everyone saying if they didn´t know you were there . . .

The Talbots are having one last party at their family home.

But Effie hasn´t been invited . . .

Effie´s still not over her parents splitting up a year ago. Her dad and his new girlfriend are posting their PDAs all over Instagram - and no one should have to deal with photos of their dad with the hashtags #viagraworks and #sexinyoursixties. Now they´re selling the beloved family home and holding a ´house-cooling´ party. When Effie receives only a last-minute ´anti-invitation´, she decides to give it a miss.

Until she remembers her precious Russian dolls, safely tucked away up a chimney. She´ll have to go back for them - but not as a guest. She´ll just creep in, grab the dolls and make a swift exit. No one will know she was ever there.

Of course, nothing goes to plan. Not only does Effie bump into her ex-boyfriend (who she´s very much not over), she can´t find the dolls. And as she secretly clambers around dusty attics, hides under tables and mournfully eyes up the dessert table, she discovers unexpected truths about her family - and even about herself.

With time (and hiding places) running out, Effie starts to wonder if she´d be better off simply crashing the party. Perhaps that´s the only way to find out what´s really going on with her family . . .
