The Sex Lives of Siamese Twins taps into two great obsessions of our time, personal training regimes and real estate – how we look and where we live - and tells a story so subversive and dark it blacks out the Florida sun.

From the number one bestselling author of Trainspotting.

Meet Lucy Brennan - an aggressive personal trainer who has just become a media hero after taking down a would-be gunman in Miami.

The one witness to the daring rescue is Lena Sorensen - an overweight depressive who is becoming increasingly obsessed with Lucy . . .

Irvine Welsh’s latest creation captures the two great obsessions of our time – how we look and where we live – and tells a story so subversive and dark it blacks out the Florida sun.


[Welsh] has never written with greater verve... This is a novel packed with energy.

Tom Adair, Scotsman

Shady, crazy and dark.


Welsh doesn’t disappoint… Bag yourself a ringside seat.

Elena Seymenliyska, Daily Telegraph

This is a visceral romp of a novel, a manic endorphin rush of a read that nevertheless also manages to sneak in some serious commentary on the state of American society, putting this book right up there with the best of Irvine Welsh’s work.

Doug Johnstone, Independent on Sunday

Not only cleverly conceived but genuinely, hauntingly, transgressive.

Sandra Newman, Guardian

Razor-sharp prose... Both Lucy and Lena dazzle in this hugely entertaining read.

Kevin Scott, List

Boisterous, exuberant.

Sunday Times

A compelling read.

Russell Leadbetter, Glasgow Sunday Herald

Proof [Welsh] can write convincingly about experiences suitably removed from his own.

David Pollock, Independent

A darkly funny novel with well-drawn characters.

UK Press Syndication

Boisterous, exuberant.

Sunday Times

Shady, crazy and dark.


A compulsive read.

John Sunyer, Financial Times

Never has filth been such fun – Welsh at his wicked best.

Sebastian Shakespeare, Tatler

Welsh’s words fizz and burn with energy… It’s crude, hot, vulgar and irreverent, but not in a smut-for-smut’s sake way – this is intellectualized scatology, scatology made into high-art… Welsh’s grist is, and always has been, to show the ugly truth of exactly who we are, with breath-taking beauty. And in that, he remains peerless.


Readers should not let the incessant onslaught of obscenity distract them from…Welsh’s poignant and well-meaning message.


Irvine Welsh maintains a breakneck pace…engaging the reader completely.

Sarla Langdon, Bay
