You haven't heard of Death Note?! ;_;
Ok, I'll quote a bit about the book itself.
"Death Note: The human whose name is written in this note shall die. After writing the cause of death, details of the death should be written within the next 6 minutes and 40 seconds. If the cause of death is not specified, the person will simply die of a heart attack. If the cause of death is written within 40 seconds of writing the person's name, it will happen immediately. This note will not take effect unless the writer has the person's face in their mind when writing his/her name. Therefore, people sharing the same name will not be affected."
Ok, so a guy sees the book lying on the ground, picks it up... and then the whole story starts from there. I don't want to spoil anything, but it's been interesting so far.
