First off, this is nothing to do with a Kraken. Nada. So don’t expect a book full of giant squid-like creatures pulling down pirate ships into Davy Jones’ Locker. S’all I’m saying. The title is pretty much because Mr. Wyndham liked Alfred Lord Tennyson’s poem, called (shockingly) The Kraken Wakes. The poem contains a Kraken; the novel does not. No other connection. No, it makes no sense to me either.
Below the thunders of the upper deep; Far, far beneath in the abysmal sea, His antient, dreamless, uninvaded sleep The Kraken sleepeth: faintest sunlights flee About his shadowy sides.
