Into the Darkness, by K.F. Breene
Spoiler:
Sasha has grown up with one surety: she’s not normal.
She sees things in the darkness that no one else can see. Mysterious men cloaked in shadow, moving through the night. The problem is, pointing out invisible people is a fast track to a padded cell. Orphaned at age five, Sasha quickly learns an important survival tip: keep her mouth shut and stay out of the spotlight.
Until one night, everything changes. She and her boyfriend, Jared, find themselves stranded on the wrong side of town. Suddenly, the men she was convinced were hallucinations, are very real. And very dangerous.
As a new world opens up around her, she meets him. The Boss. An alpha leader who entrances her mind and tugs on her body. Primal and sexual, his people have a different set of rules. And they don’t always play nice.
As danger rises up around her, her differences may be the only thing that saves her life. She must embrace what she’s tried so hard to hide, while resisting the person her body craves most. Sasha has finally found her shadow men, and they will change her life forever.
