Summer Princess by Sloane Murphy

She’s marked for a life she doesn’t want. He’s the one compelled to make her comply.
Emilia Daarke has fallen in love with the one person she should never have. After being caught by her father, she is thrust into a deadly game she must win, not just to save herself, but the ones she loves the most.
When Cade Vasara sees the girl he once loved, the one that got away, he’s torn between love and duty.
With betrayal and secrets running riot, and a ticking clock against them both, can they set aside their past, or will their present tear apart their world?
