"Careful, little stepsister," he whispered, his breath warm against my ear. "You only get one free shot." I should have walked away. I should have focused on my mother's cancer treatment and my Columbia classes, I should have ignored the way Kelvin looked at me like he wanted to devour me and hate me at the same time. Instead, I met him in his room at midnight. I kissed him back when he cornered me in the hallway. I fell for the one man I could never have. Now someone is watching us. Photographing our stolen moments. Blackmailing me with evidence that could destroy both our families. If I don't stay away from Kelvin, my mother loses the medical care keeping her alive. If I do, I lose the only man who's ever made me feel this alive. Elena Martinez thought moving into a billionaire's mansion would solve her problems. Instead, she found Kelvin Hartwell—cold, devastating, and convinced she's a gold digger. One forbidden kiss changes everything. But when blackmail, kidnapping, and corporate espionage threaten to destroy both their families, Elena must choose between protecting her dying mother and the man she's falling for. Some obsessions are worth burning the world down for. Ours might just do exactly that.
