Flicker

Being unable to move on in your afterlife is... pretty lonely. Most can  go straight on to what awaits after, but not Flicker. Having been the  first of many, many disappearances in the woods, their soul cannot rest  until the mystery of the forest is solved... which would come much  sooner if only they could remember anything beyond entering the  treeline. Enlisting the help of Oriole, a brave young cat who can speak to ghosts, and her energetic younger sister Robin, another victim of the woods, the trio set out to uncover what really happened to everyone who was lost to the forest.
