Cold Hard Kisses (London Mafia Kings Book 1)

When innocent Hallie is given to Tam Cornell, the eldest brother of a British crime syndicate - and her father's biggest enemy - as a bride, she quickly learns he's not so keen on the idea of marriage either. He gives her thirty days of living with him to see if she can handle him, before he'll marry her. Except Tam doesn't realise she's more of a match than he's bargained for.
