Carides's Forgotten Wife by Maisey Yates

Once forbidden, now for bedding! 

Greek billionaire Leon Carides has it all: wealth, power, notoriety, even a wife–though he's never touched his convenient, innocent bride. Then an accident rids this damaged, debauched playboy of his memories… 

Leon remembers nothing, except his wife's sparkling blue eyes. Now the desire he feels for Rose overrides the gaps in his past, making her impossible to resist! But when his sins catch up with him, can Rose forgive the mistakes of the man he once was? Or will Leon lose more than just his memory?
