What is the best way to promote a new book to the 16-26 age group?

[Natalie]

Start a blog about backpacking and write two or three posts a week and submit them to your Twitter and Facebook accounts. Advertise the book on your blog.

Or, put together some video presentations about backpacking and upload them to YouTube. Put a link on your YouTube video page to the page that you've designed to sell the book.

Write a sales letter (or hire someone to write it) selling the book. I wouldn't make it too long because this age group has a very short attention span, but you need a site to send people to so you can get them to buy the book.

Hope those suggestions help. Good luck with you book.
