Glowing Alien Lake

Publisher's blurb:

Alien trees with green flowers cling to a series of steep cliffs that descend into a glowing, purple body of water. It’s filled with schools of fish, disk shaped pink and violet plants, and leads down into darkness.
Naturally formed stone bridges reach out across the liquid, lined with strange, tubular purple and red growths that glow eerily. Ruddy wildflowers cluster at their base, amid rocks and jagged outcrops.
Fallen stones crunch underfoot, while the fish occasionally fly out of the water; calling strangely before diving in again.
