I have never read this book in the Goosebumps series so I was just as excited as K to start reading it. For me this book didn't seem scary at all. You know the cover has a shark so I was thinking it had to be about a shark right? We see how Billy Deep the boy who loves to use his imagination on go on adventures within the ocean. Though what happens when he learns that there is something in the lagoon where his uncle is at studying the sea life? I think for K and I we enjoyed the ending where we wonder if they will all believe Billy now as it seems that he really sees something within the sea. There is adventure, mermaids, and deceivable people lets see what happens next!
