Is The Fault in Our Stars by John Green Worth Reading?

"The fault, dear Brutus, is not in our stars, but in ourselves."

- William Shakespeare, Julius Caesar

I haven't read the novel, The Fault in our Stars, by John Green. I've also not seen the movie version as well. I know that a lot of people has attest to the poignancy of the story but I still need to be convinced and motivated to pick up a copy and read the book.

How can you convince a 30-something to read a novel that was originally designed for Young Adults? Would I be able to relate to the characters? How about the story? Is it something that would appeal to my generation? Do you think I would be able to enjoy reading it? 

If you've read the book or seen the movie, how would you influence me to make the decision? Feel free to reply through the comments box. I'll be more than happy to get your thoughts about this...
