Just how far will she go to keep her secret crush?

I'm Kayla.
I'm twenty-one.
And I'm all alone in the world—except for my late brother's best friend.
But Oliver intends to move back to London.
I'm in love with him. I have to persuade him not to leave...somehow.
If I confess I'm a virgin and show him how far I'll go to keep him, will he stay?
Maybe, but I also never suspected he's keeping a shocking secret of his own...
