Woah...what just happened?

Have you ever read a book where in the beginning, you have no idea what's happening? I bet you have. But have you ever had a book where, a guy commits suicide, the main character wakes up in the hospital with a gunshot wound to the head and no memory, and the doctor gets shot in the chest by a mysterious woman with spiked hair? I don't think so; unless you've read The Lost Symbol by Dan Brown.
"Langdon watched in horror as Dr. Marconi staggered backward into the room, falling to the floor, clutching his chest, his white lab coat drenched in blood." (25)
That was the last sentence of Chapter One of The Lost Symbol. This author sure knows what he is doing, because from that point on, I was hooked to that book. You have to have good beginning to get your reader hooked. Without a good beginning, it will be slow and it will be hard to get your reader to keep reading your book. I have personally stopped reading books because it was so hard for me to get into it. If you ever right a book, and I highly doubt you will, but just in case, write a good beginning that stays with the reader and makes them blog about it!
