Husbands: you're really only allowed one at a time ... Bella secretly married Stevie, over a decade ago; they were at university, two big kids playing at being grownups. When it all unravelled and reality hit, Bella simply got up and left. Years later, Bella meets Philip and, despite her vow never to marry again, she can't resist him. He is a catch. Funny, charming, interesting and kind. Only hitch is, she's still (technically, anyway) married to Stevie. And the moment to tell Philip never quite seems to arrive. So Bella plans never to reveal her secret — after all, it's just a silly piece of paper, lodged at a registrar's office in Aberdeen, isn't it? She hasn't seen Stevie for years — probably never will again. Except when Bella's best friend Laura introduces her new man to the gang it is none other than Stevie. Could things get any more complicated? Only if Bella and Stevie fall in love with each other again...
