Crazy for You by Virginia May

“I might have – slightly – said I was married. To you.”
Jordan has been in the shadow of her older sister all her life. In one unguarded moment she makes a rash boast – that she’s married. But then her sister announces a visit and it’s up to Jordan to make the lie at least appear true.
Alex is tired of friends describing him as “Mr. Beige”, so when Jordan throws herself on his mercy, he decides now might be the perfect moment to do something crazy.
Except a weekend of pretence might not be enough – for either of them.
