Grendel Rising
by Gordon Phillips
Grendel is a troll who comes up from the world below, to find love. But the passage is hard, and it is only with the aid of Ken, a thirtyish software engineer, that Grendel survives. There is an immediate attraction, but if they are to have time to explore this, the pair must find a way to elude the FBG (Federal Bureau of Geostasis), which views Grendel’s presence above-ground as intolerable.
