Indecent Demands (Dark Knights Book 1)

My stepbrother hates me. I need his help. What he expects in return is unthinkable. A predator called Casanova has transformed my university campus into his hunting ground, and I'm his next target. I turn to the most powerful person I know, but my gorgeous stepbrother wants to bring me to my knees. Literally. (An enemies-to-lovers dark romance.)
