I liked it. Other people mentioned it feels weaker than the first two, I didn't really feel that, but I like sea/pirate/etc stories. (Even though this is technically a lake.) I liked that they had a new kid joining them, and the stakes are raised a bit, since adults actually die in this one?!

What really disappointed me was that 20% of the ebook is an excerpt is the next one. I felt cheated by this, because you think there's 20% more story, and then suddenly it's over.
