The sea is full of saints.
Billy works in the Natural History Museum in London. The book opens with him running through his usual spiel on the exhibits of Darwin House, but he knows what everyone has come to see. The giant squid is the highlight of the tour. Trouble is, it seems to have gone missing! Which is impossible. I mean it is a giant squid in a giant tank, why on earth would anyone want to steal it. And how? But gone it is. And all of a sudden Billy finds himself in the middle of a London he knows nothing about. Where people with knacks might help him out, or quite possibly be about to bring about the end of the world. A world with Kraken Gods, and speaking tattoos, and gunfarmers, and invisible piggy spirity things.
I really loved this book.
