A terrible heatwave. A very tense baby shower. It will all end in tears...

Nicki, Lauren, Charlotte and Steffi have been friends since university. Now in their thirties, life is pulling them in different directions - but when Charlotte organises the baby shower of hell for pregnant Nicki, the girls are reunited.

Under a sweltering hot summer day, tensions rise - and by the end of the evening, nothing will ever be the same. Someone started a fire at the house - and everyone's a suspect... Is it Steffi, happily child-free but feeling judged by her friends? Is it Charlotte, desperate to conceive and jealous of those who have? Is it Lauren, who is finding motherhood far, far worse than she imagined? Or is it Nicki herself, who never wanted a baby shower anyway?

In the aftermath, the police put together the facts - but the truth will shock everyone. Even you.

BIG LITTLE LIES meets REALLY GOOD, ACTUALLY in the incredible new novel from Holly Bourne - it's the book you'll want to read three times, then give to every woman in your life.
