They Came From Below by Blake Nelson
This was a neat book and I'm giving it a YAY for now. Writing in a concise, matter-of-fact style, Nelson follows 17-year old Emily and her friend during summer vacation on Cape Cod. The combination of some strange things in the ocean and two "tourists" who don't seem quite human turn their vacation into an adventure. There are a lot of cool characters in this book and some very minor characters are fleshed out. It did not overwhelm me, but this is a cool combination of adventure, sci-fi and quirky realistic fiction.
