The second book in the "update" of the classics craze, SSSM falls a bit flat compared to "Pride, Prejudice and Zombies." It follows the same simple formula - keep the same basic story, plot and dialogue, but add in a bit more of a zing. In this case, all the creatures of the sea (for many reasons speculated, but nothing ever clearly determined) have been changed into bloody thirsty creatures who want nothing more then to destroy humanity. England, as well as presumably, the rest of the world, exists in a state of trying to survive the way they always have while trying to defend their lives against the monsters, and trying to genetically alter and train the monsters to stop killing them.

The ultimate problem with the book is that it tries to hard to mix in the new storyline, and it doesn't flow that well. PP&Z did it much better.
