The Malykant Mysteries Books 1-4

The Bone Forest at night is a dangerous place to be. The ground is marshy, spread with silent pools of water waiting to catch the steps of the unwary. A permanent fog shrouds the air in the colder months; in winter little can be seen of the landscape save the twisted trees looming out of the dark, their branches reaching into the sky like stripped bones.
Once in a while, though, the moon shines briefly from between layers of heavy black cloud and the mists gleam bone-white in response. And even more rarely, a flicker of ghostly white near the black earthen ground begs to catch the eye: a glimpse of a marsh spectre, so easy to miss.
The marsh spectre is not, as might be inferred, a spirit but in fact a flower. It grows in only the wettest of marshes; were its delicate petals to dry out it would crumble and fade into the wind like a wraith.
