A scientist named Jonas Taylor runs into something in the Mariana Trench that scares him. So much so, that it costs the lives of the two Naval scientists with him. From that point on he becomes wary of the deep sea, but completely addicted to the study of Carcharodon megalodon, the prehistoric cousin of the great white shark. He swares that a megalodon lives in the Mariana Trench, but cannot prove it.
Ten years after his accident, Taylor is given another chance at the Mariana Trench. This time, he is asked to help out a friend hoping to recover damaged equipment deep within the trench. Taylor agrees to help, not without reservations. From this point on, the story picks up at a nail-biting pace that makes for a great read.
The description of the Meg and her vicious attacks are so vibrant that you can easily see them in your mind. It's obvious that much time and research was put into this novel by Alten.
