Sacrifice by Rachel Kane

Rian has always been Marco’s protector. Abusive parents, school bullies, older creeps–Rian took them all on. Anything to protect his stepbrother. But what if the person Marco needs protecting from, is Rian himself?
For years, Rian tried to deny his need for Marco. To tell himself his desires were wrong. Filthy. Forbidden. But the moment Marco confessed he had the same desires, Rian ran.
It has been three years since Rian saw his stepbrother, and now Marco needs his help more than ever. Selling his body, losing himself in drugs, drowning in shame, Marco doesn’t want Rian to see him like this. But when gay teens across the city start disappearing, there’s no one else he can call. A demonic cult is preying on society’s most vulnerable boys.
These days Rian has found a new way to be a protector; he has joined a team of vigilantes who are keeping the streets safe for Rushton’s gay youth. He knows he can’t get close to Marco, can’t reignite the dangerous desire inside him…but he and his team are the only ones who can help. Rian once swore to keep Marco safe—but is he strong enough to fight the ache inside him? Or will he finally give into his darkest needs?
