Query: An exciting page-turner for the summer, or anytime!

Alten has crafted a tale with all the elements of a summer page-turner. The characters are well-developed whether they are heroes or villains. What I liked most about them is that they are not stereotypical. The villain of the piece is one who provokes valuable questions in the reader's mind. It's these questions that sometimes challenge the heroes in the story to question their own motives. The book is also big on action. It uses bits of submarine tales, espionage, humor, and a touch of sci-fi to keep the reader hooked. There a are several twists which will keep you guessing right until the end, but don't look at the last page!!!All in all, I had fun reading this book and felt like I got my money's worth. We all work too hard to plunk down our money for a book that doesn't hold our interest. Goliath held me from page one. It's exciting, fun, and thought provoking. Buy the book!
