Description

'With her renowned clever wit and masterful (mistress-ful) wordplay, Lette delights us all yet again. Read this and know you are in the hands of a wise feminist who makes you laugh out loud!' Suzie Miller, award-winning author of PRIMA FACIE


The Sisterhood Rules:

1. Never let a man come between you

2. Share all your secrets
3. Live life to the fullest - girls just wanna have fun

For twin sisters Isabel and Verity, the sisterhood rules were shattered when Verity had an affair with Izzy's husband. Unforgivable, right? Devastated by her sister's betrayal, Izzy casts Verity into social Siberia.

But when their mother goes missing, Verity and Izzy are forced to come together again to find her. And then the estranged sisters' problems only get bigger. Their mother has a new younger lover and where there's a will… he'd clearly like to be in it.

Can they stop their mother making a dreadful mistake? And in doing so find a way to bury the pain of the past?

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 that nothing is more important than your sisters.

What a absolute riot! This book had me laughing like a hyena. The quick witted word play is fabulous. The characters are well regulated with their banter and the relationship between them.

A really fun read. Made me smile from the first page. Family divided, 3 generations of a musical family. Divided by a male.
Twin sisters who love the same man, one who he married and had a daughter with, then leaving her for the twin sister.
A rift of 5 years is only put aside when their mum goes AWOL.
Full of twists and turns. Enjoy I did

I have been reading Kathy Lette books since the Llama Parlour in the 90’s. I love her style and wit and it simply doesn’t age. This book does not disappoint. Always a pen array of familiar yet strong characters who refuse to let life’s struggles get in the way. Another triumph. Thanks for making me laugh out loud, usually in public.

Another laugh-out-loud book from Kathy Lette. This story of forty-nine-year-old Izzy and her estranged twin sister Verity, as they deal with a mother who's gone AWOL, is filled with witty one-liners - I particularly enjoyed the concept of f*cktose intolerant. If you love seeing the funny side of less-than-perfect family relationships and women dealing with the challenges of middle age, raising teenagers and wayward exes, this book will keep you entertained.

oh someone should have taken a picture at the side of my immediate grin when i saw this beautiful author had another book. it came across my scroll and i immediately backpedalled in a fashion i think she would appreciate "waiiiiiiiit a minute there" my eyes readjusted when her post flickered back into my screen. and there it was. a new book. and boy i need one of her right now. smile at the ready even before i began. i could already here her voice waiting for me. i could already picture the feel good moments i was going to have. and that is when you know an author has magic in them. i wasn't even reading and i already felt better! come on, that is magic.
so really you dont need my review. im not biased. if an author falls of a cliff with their writing i wont lie. but i wasn't worried. and nor should i be. this was another wonderful read. so funny. so witty in that dry and sarcastic way that hits my core and makes it laugh. but also connecting. also somehow reflective and makes you think and feel and does so in a way that it just feels ok to do so.
you care for these characters. you know Kathy does. and that in itself feels like you are being cared for by this book, by this read. because it just feels better to be reading it.
dont get me wrong. this isn't without some themes and some really deep stuff going on. i mean eeeesh.
our two estranged sisters are like that for a reason. and it made me almost emotional from the start when you read why they got there. and are we already picking sides?
but their mother is now missing. soooo what you gonna do. well of course you need to come together. but was i still on my chosen side and feel begrudged that one sister had to? ermmm maybe.
but money is a force to be reckoned with here. not least when a younger man is after it. they know they have to stop their mother being swindled.
Izzy and Verity quickly made me feel for them both. and quickly made me want to support them both with helping their mum. i mean dont mess with our mums right? but that doesn't stop the lingering resentments or feelings that feel pretty huge at times.
this was just the book i needed and it came at the right time.
there is all the charm from the author we have all come to love. but also the knowing, the feelings, the way you can still get emotional for whats going on. perhaps even more so because of how Kathy gives us access to it.
you need to get into these books. and when you do you will find the groove and find the love for them. all those years ago i admit i was a bit "closed in" about it. it felt too loud for me. but ha, a fair few years(and more) and a fair few years of Kathy and it feels like i just know her words, manner and style and it feels like coming home each time. it feels like i can be safe in her words. she IS who she is, and that has become more important to me over the years, and made me love her and her work even more.
