With bloodshed and banter, Billy masters supernatural horror.

Hellion book on paperback and Kindle

The Immortal Sloan series continues with Hellion.

After an innocent Sunday stroll, Elizabeth wakes up in a world she doesn’t recognize. Her journey to the truth is a path strewn with bad guys and body parts.

You don’t have to read Ordo Tenebris to pick up this sequel. It reads just as well (and just as violently) on its own.

Watch out for the third and final book of this series, where all the storylines converge for an action-packed finale.
