Hallow Hills by Olivia Isaac-Henry 

Don’t miss the next dark and creeping folk horror tale from the author of Sorrow Spring

Have they stirred an ancient evil…or is there a killer in their midst?

Twenty years ago, on Halloween night, a group of teenagers performed a summoning ritual on Hallows Hill.

The next day, one of them was dead.

Mia has never forgotten the chilling vision she saw that night, and which she believes foretold the death.

Now the remaining friends gather for Halloween again.

But when another death occurs, Mia starts to doubt everything around her. Is there a malevolent supernatural force that means them harm, or is human evil at play? Mia must take a long, hard look at her friends, herself and the folklore of Hallows Hill.

Can she find the answers before all of them are dead?
