The Sisterhood Rules: Ah, so many, but the most important three?
1. Share all your secrets – trust is everything
2. Never do the dirty on her – in life, but especially in love
3. Be there for good and bad – nothing, especially a man, is worth losing her over
For twin sisters Isabel and Verity, the sisterhood rules were shattered when Verity had an affair with Isabel’s husband.
Unforgivable, right? Devastated by her sister’s betrayal, Isabel vowed never to speak to her again and for five years has kept her promise.
But when their mother goes missing, Verity and Isabel are forced to come together again to find her, and when they do they realize their problems are about to get worse.
The only question is - when the person you once loved the most is now your mortal enemy, can you ever find a way back to what you were?
After all, if the sisterhood is to rule, then surely you have to follow all the rules?
Full of laugh-out-loud humour and devastating pathos, Kathy Lette’s brilliant new novel takes us on a roller-coaster ride which proves that from pain comes healing, from honesty comes forgiveness, and nothing is more important than your sisters.
