Love & Other Forbidden Things by Lyndsey Gallagher

Amy Harrington is struggling to readjust to life at home in Ireland after the cosmopolitan buzz of London. Sick of being the only singleton on the shelf, she longs to find the right man, but the second any potential candidate realises who her famous rugby playing brother is, they spend more time worshipping him than her.
Irish rugby player Ollie Quinn is newly single and ready to mingle. When he meets a brunette in the players’ lounge, he promises to show her Ireland can be every bit as exciting as London, before realising she’s Eddie Harrington’s little sister. Despite the explosive chemistry between them, it’s one promise he can’t keep – everyone knows messing with your friend’s sister is forbidden.
When Amy lands her dream job, physiotherapist to the rugby team, the two are forced to face the growing chemistry between them. Injuries on the pitch seem minimal compared to what Eddie might do if he discovers their dalliances.
Is it simply the temptation of tasting forbidden fruit?
Or will forbidden turn into forever?
