From publisher blurb:
Ghastly green spectres are flooding out of the Shadow Deep in the north, overrunning the Alladorean army and putting it to flight. Now, two groups of rangers must work together to launch a daring, and likely deadly, raid into the heart of enemy territory. But with an entire army between them and their target, can the rangers really hope to destroy the Ghost Stone?
Rangers of Shadow Deep: Ghost Stone is a four-scenario mission in which the player, or players, control two, different ranger groups on a desperate mission. The book also includes 52 unique, enchanted weapons that rangers can find during their explorations, several new monsters, and one unique auxiliary companion.
