The year is 1717, and pirate Captain Scarlet MacGrath wants nothing more than a decent meal, a glass of rum and a good man waiting for her in the next port. But life rarely works out that neatly.
When the rum runs out, Scarlet sets sail for the mainland to look up an old friend. But friends turn into enemies pretty quick in this part of the world, and before long Scarlet, her crew, and the good ship Donnybrook are caught between the lawless Donnelly boys and the bloody-handed Red Ned Doyle himself. Can Scarlet use her Irish charms to free herself and her crew, or will it be cutlass and cannon?
Would you change it?

A blurb is the thing that goes on the back of a paperback book, so that people will read it and want to buy the book.
A "hook" is more the beginning of a book, where the story starts to get interesting.
