Forces from Beyond is the sixth and final book in Ghost Finders series written by Simon R. Green. It stars a second string team in the Carnacki Institute, who hunts ghosts.
The Ghost Finders from the Carnacki Institute reluctantly join forces with their rivals Project Cowley to battle a major threat to humanity – The Flesh Undying, an inter-dimensional monstrous being with unimaginable powers. Matters get complicated when the very creature under the seabed dispatches an assassin against the Ghost Finders, who has a deadly vendetta against them.
Forces from Beyond is written rather well. The narrative wraps up the story lines and series rather well and positively brims with details that mark it as being in the same reality as the other Green series, be it a Hand of Glory made from the remains of Drood or one of the characters turning out to be the granddaughter of a Nightside recurring character.
Overall, the Ghost Finders series is a moderate one. It started off rather slow and mediocre, but improved as the series continued on. On paper, a rag-tag team facing off against ghosts and inter-dimensional creatures seems like a good and humorous idea. However, in comparison to his other works, these powerless people fall rather flat at moments. While not my favorite Green series, it is rather well done nevertheless.
All in all, Forces from Beyond is written rather well and is a good continuation to a moderate book series.
