Dangerous (Darkest Powers, #0.5) - Kelley Armstrong This is part of Kelley Armstrong's free online fiction. The stories can be found here.This story explains how Derek and Simon's Dad disappeared, and how they wound up at the Lyle House. It was interesting and written well for such a short story. It was good to hear more about Derek as he is my favorite character so far in the Darkest Powers Series.Entertaining. :)
