Chasing Harry Winston is a major novel by Lauren Weisberger, author of The Devil Wears Prada. Harper Collins chose us to handle a Facebook promotion for the launch - making sure those online pages were spreading the word about the paper ones.

We created a fan page, enticing users with exclusive sneak previews of the book.

Then to maximise Facebook's viral potential, and inspire greater involvement, we added some book-related promotions:

• Amazon voucher codes exclusive to fans of the page
• The chance to win a trip to NY (where the book is set)
• Free books and DVDs for users who posted their "must have accessory" on the wall.
