Anyone who has read my work for a while, particularly my gamebooks, will know that I have a bit of a thing for cephalopods.
I have always been fascinated by these highly intelligent, boneless mollusks, starting with legends of giant squid. In fact, I even have a print of a giant cephalopod on my wall. I based this image from my map of Neverland on the self-same print.
I should warn you that there are minor spoilers ahead...
There is a Giant Octopus in Bloodbones, the Abyssal Horror in Stormslayer shares some features with a giant cephalopod, there's the Terrorsquid in NEVERLAND - Here Be Monsters!, and a Kraken in Beowulf Beastslayer.
One of my books - Doctor Who: Night of the Kraken - even has a cephalopod in the title. And there are squid or octopus-like creatures in 'TWAS - The Krampus Night Before Christmas, Dracula - Curse of the Vampire, and RONIN 47. And that's just the gamebooks.
Something very much like a giant squid gets a fair bit of screen time in the second Ulysses Quicksilver Pax Britannia novel Leviathan Rising, and there is a fantastic illustration of a Kraken in Heorot - Roleplaying in the World of Beowulf Beastslayer.
Will there be octopuses and giant squid in future books? Undoubtedly!
