Cover blurb
There's a ship out there, on the ocean.

She's called Lankester and, every year, she sails from Madagascar to New Orleans and back again. Every year. Without exception. Regular as clockwork.

Her schedule is never behind. Her cargo is always fresh.

This trip, she has passengers. The passengers have baggage.

And the baggage might just be enough to sink her...

This story takes place between The Trial of a Time Lord and Time and the Rani.
