The ideal stocking filler, as long as your stockings will take something 148mm wide. 
Amber A'Lert, a notorious local writer has written this rather interesting book and it's illustrated to a spectacular degree. 
It contains 32 pages, full of possible ferry cancellation excuses for 2024 and probably beyond.
From dolphin navigators to unexpected destinations, you should treat this as a fun way of letting off some ferry frustrations.
