Definitely the antidote to H P Lovecraft. British author Lumley takes the 'Cthulhu Mythos' of American Gothic author Lovecraft and asks, How would it be if the monsters and alien space gods of the Mythos were all a bit, you know, 'meh', and humans could kick their Cyclopean backsides? And the answer is: very stupid indeed.
On the plus side, Lumley makes some positive contributions to the Mythos in the forms of the earth-burrowing Cthonians (think: giant telepathic subterranean squid-worms) and sea-Shoggoths. On the negative side, the Miskatonic University is now S.H.I.EL.D., Elder-Signs keep Mythos monsters at bay like crucifixes repel vampires, and Lovecraft's brand of cosmic existential dread has been fixed by the brisk intervention of the Civil Service. On top of this bland pastiche, we have to suffer the main protagonist (though not, mercifully, the main narrator) Titus Crow, who is one of the more annoying Mary Sues that fan fiction has thrown up.
Look, it's an easy read. The Wendy-Smith digression on G'harne, Cthonians and the burrowers beneath is actually a taut and satisfying novella. But overall, this is lacklustre stuff.
