Bad Behaviour

A Story of Friendship, Betrayal, and Sweet Revenge

Bestselling author Sheila O'Flanagan delivers another compelling novel with Bad Behaviour — a page-turning tale of deep friendship, lost love, and long-awaited closure. Full of emotional twists and rich with relatable characters, this 2008 release is a must-read for fans of women’s fiction.

When the Past Comes Back to Haunt You

Darcey and Nieve were inseparable — best friends through thick and thin, travelling through Europe and dreaming big. But everything changed the moment Nieve returned home and stole the heart of Aidan, the man Darcey had fallen for. Aidan had planned to propose... until Nieve caught his eye.

Ten years later, Darcey has built a successful life, but the sting of betrayal never left her. Not even her marriage or her quirky, loving family can erase the heartbreak. Then the unthinkable happens: an invitation arrives — to Nieve and Aidan’s wedding, in Ireland’s most lavish hotel.

Love, Loyalty, and Letting Go

With her trademark warmth and wit, O'Flanagan explores whether old wounds can truly heal. Will Darcey attend? Will she find peace — or ignite fireworks? Bad Behaviour is a gripping exploration of love, revenge, and the ties that bind... and break.
