Maybe it was a book of fiction as Carnival never had a ship named Horizon--Celebrity did --It was the first new -build ship for them.
Sounds like he maybe pieced together some fiction and called it a book.
All the same old jokes have been around for years but a lot of folks, especially first-time cruisers fall for them--does this elevator go or down--one fellow packed all his clothes the last night and sat them out--had to wrap a towel around himself at disembarkation and of course we couldn't let him take ship's property off with him and etc.
Hopefully the aspiring writer will eventually find his niche.
I have heard the same old jokes in all of my 15 cruises.

So many books make absolutely no money, and it sounds like these are two of them.
When they make the NYT Bestseller List you might have reason to grouse, but I think there's little danger of that. More likely they're self-published, that is to say, vanity published. If not, the publishers will undoubtedly take a loss, and the authors will get nothing more than their advances--which for first timers generally doesn't pay the rent for very long.
Not to worry. The marketplace will decide.
