According to her bio, two-time Aurealis award winning Fantasy novelist Jane Routley has had a variety of careers, including fruit picker and Occult librarian. She is also a tabletop gamer. After many years playing Call of Cthulhu, she's turned her hand to scenario writing with Prowler at the Threshold, a Modern adventure about university students experiencing the pleasures - and the horrors of living in a share house!

The Forest
Michael Bertolini ($3.99, 13 page PDF)

Forests are, traditionally speaking, a different world spilling into our own. Not only do the forests house animals and plants unseen and unknown to the modern world, but they are often a barrier between worlds; there are forests in the world that, once entered, do not exit back into our world. Some forests don’t have an exit to speak of. But as civilization has grown, forests are destroyed in favor of progress. In a particular forest in Germany, unnamed and forgotten by many, the forest is a mystery; it has established a reputation for evil.

The investigators have unwillingly entered this unnamed forest and must uncover its secrets if they want to escape. Modern-day scenario taking place in Germany in the summer of 2020.
