Picture this...

[Spiner909]

I publish the book and make massive profits off it.

My life is awesome, therefore my death will be awesome

Brilliant! This.

 

[Kamaitachi]

I publish the book and make massive profits off it.

My life is awesome, therefore my death will be awesome

This.

 

[Yumi_and_Erea]

Throw it on the pile, I s'pose.

 

[kilibot57]

Make a movie about it

 

[Aesir23]

Read it, if I know HOW I'm going to die then it will lend some certainty to my future and I will feel more prepared when the hour of my death arrives.

 

[Frank_Sinatra_]

I'd eat it, then I'd become Death itself.
BWAHAHAHAHAHAHAHA!

 

[Agoreophobe]

BIG fish

 

[the1ultimate]

Well, I would read it.

Knowing is always better than not knowing, right?

Also, there is always the possibility that I could change it, unless it says "Dies peacefully in sleep, aged 112 surrounded by family and friends."

I might also consider burning the book, since it's no worse than I've done to other books whose endings I despised.

 

[Beartrucci]

What do you do with the book?

Sell it. Some sucker into fortune-telling and stuff will probably pay good money for it.

More than likely this, because this idea is made of win.

 

[Simalacrum]

you know, looking at all these answers, its quite strange to see that everyone automatically presumes that the book tells truth, just becaus they're mind tells them so...

 

[ArcWinter]

Argh! You've changed the conditions!

For this new and uncertain model, I'd probably start eating the book. Mmmm, knowledge.

 

[primitivescrewhead]

Throw it away

 

[historybuff]

I'd probably assume that it was bullshit and read it anyway.

I'll take the book, walk up to a random person, hand it to them and say, "Written in this book is how you will die." Then I will walk away.

Although this would be more fun. Haha.

 

[NuclearPenguin]

I would read it.
If it said something like "You will die taking a shit with a laptop while browsing the escapist." I would motherfucking make a god damn heavenly thread and go take a crap, bringing my laptop into the shitter with me.

 

[Davey Woo]

I'd look at it.
I wouldn't try and avoid my own death though, unless it was like "eaten by a shark", it's relatively easy to stay away form sharks.
