Second instalment about the adventures of this quirky, off-beat comedy duo – a boy scribe and a kick-ass granny.

"I have not long now. The fire is dying and I can hear their teeth rattling in the darkness..." When eccentric young wordsmith Samuel Johnson stumbles upon a page torn from an ancient notebook bearing these words, his interest is piqued. And the words seem to have a strange effect on Granny Samurai, leaving Samuel with an uncomfortable sense of looming doom. He doesn't have long to wait for his fears to be realized: on the day of Samuel's birthday party his friend Philip is accidentally sucked through an errant wormhole. Before you can say "Megawocka!" Samuel and Granny Samurai are on a dangerous rescue mission that leads them to a mysteriously bleak island in another dimension. But wait, that's not an island – isn't that a giant, pulsating ... brain?
