"All Emily Windsnap wants to do is impress her best friend, Shona, and the other mermaids who live in the sea around Allpoints Island. But instead, she wakes up with the kraken, a terrifying octopus-like monster the size of an apartment building. Now he's coming after everything and everyone, and it's up to Emily to stop him. Luckily she's got help from Shona and one other person--someone Emily hoped never, ever to see again."--Back cover.
