From publisher blurb:
Perilous Horrors in a Hidden Jungle Temple!
Few dare to brave the dangers posed by the Jungle of Zaal. It is a tangled place crowded with overgrowth, dangerous wildlife, and carnivorous plants. Few that enter are ever seen again and the ones who do survive its many perils emerge with fevers and madness, their unhinged accounts speaking of strange ruins infested with stranger inhabitants, old magic, and terrifying monsters.
