From publisher blurb:
The art of golem crafting does not belong solely to mages and dwarves, working with dead stone away from prying eyes.. In fact, the Forgotten Druids of the Vale developed a technique of crafting golems from living plants. Considered more reliable than taming elementals, this process created servants who might guard sacred locations, or defend children well into adulthood.
Trouble is, the Forgotten Druids may be forgotten, but their golems stayed behind. And unlike their stone cousins, they continue to grow.
If the forest they were originally protecting still stands, these golems will stay out of harms way. But if it was destroyed in a forest fire or logging operation, they might wander until they find a landscape which looks more familiar - even if their path takes them through a populated city. And since many of these creatures now tower above the trees horizon, they can become a problem which only brave adventurers can solve.
