I love this book because it was like very horror like to sci-fiction to me which i love. Although i am afraid of scary stuff when it has sci-fiction in it it puts the spark in the book that makes me want to read it until i'm done. This book is about somehow a future human spaceship landed back into our time and scientist are trapped inside some sort of their own nightmares under 1000 feet of water with no help until a week later. It actually freaked me out at first when i read it because the horror stuff actually got to my mind and gave me images but like the character took it bravely but some died which was too bad for them. The main characters barely made it out with their lives and it took a toll on their mind. The conclusion was really good at how they ended this threat that they had no idea what it could do from underwater. I won't spoil it but it involves magical powers in it kind of that messes with the mind and provides a good source of entertainment as i read the book.
