Flick is now a badge-wearing member of the Strangeworlds Travel Agency, so when an urgent summons arrives at from Pirate Queen Nyfe, she and Strangeworlds Society guardian Jonathan immediately pack their bags for an adventure to The Break, a world of magic and piracy.

Nyfe's world is falling apart. The Break is used to having ships vanish without a trace, but there has been a sudden increase that can't be explained by giant squid or merpeople. The edge of their flat world is coming ever closer to them and they need to escape before it collapses entirely.

But how do you sail a ship through a suitcase? Or fit in a mer-queen the size of a whale? Flick and Jonathan must find a way to transport the inhabitants of the Break to another world before theirs disappears forever.
