The Soul Spark

There are things in this world that are made to frighten us.
Like our own nightmares, they transform into hideous killing machines and escape into the night to come hunt us... And they take our souls for power. Which inevitably means that we are sooooooo very dead.
Hope Simmons was born into this world for one reason: to spark. These killing machines have no souls. They cannot feel- and only one has the potential. He ran away long ago from his monstrous father and since then he's been best friends with Hope. But when the Soul Collector realizes he has a Spark, the killer has to leave, for an undisclosed amount of time... 9 years pass and he's still not back.
Will he come back to Hope? And what even happens if he does?

Well, unbeknownst to Hope, she's about to find out, and it's going to be the biggest adventure of her life.
