Terror Reigns in Sherwood Forest ...

From acclaimed author Chelsea Quinn Yarbro (writing as Trystam Kith) comes the second book in the Trouble in the Forest duology, a medieval fantasy that turns legend into horror. Deep in the forest, trouble is brewing. No one is safe in the thick, dark forest—no peasant, monk, minstrel, merchant, traveler, forester, or King's man may go into the forest without taking his life and his soul in his hands. Those who dare the deep green are found dead soon after, or worse–disappear. Only former Crusader Hugh deSteny is prepared to lead the fight against the bloodthirsty denizens of the forest, and he knows that the enemy he faces could damn him eternally if he loses the battle. Armed with precious knowledge, deSteny must undertake the fight of his life to preserve the forest and all who live within it from certain catastrophe - and a fearsome enemy the likes of which none save him have ever faced before.

Demons of the Night:

... dangerous undead creatures roamed the forest, preying on good Christians and turning them into worse than devils, lost to salvation and redemption. It was all very well to praise the Virgin, and to eat bread and meat, but what good would that do if the outlaws and all their fell brotherhood were allowed to go unchecked, until all of England was in their sway? She managed to keep these thoughts to herself, but discovered she had lost her appetite.

Dutifully she ate, for it would insult the Prince to refuse his food, but it was as tasteless as rags, and the wine she drank might have been sour milk for all the lift it gave to her heart. The thought of another journey through the forest filled her with dread, but she did her best to steel herself for the ordeal to come.
