If you are selected for an influencer campaign, we connect your book with the fully vetted influencers in our own in-house network of professional book influencers.  The cost for a campaign depends on the number of influencers that choose to read the book. A campaign is considered viable when 5 influencers accept the invitation to read your book, but if more than 5 express interest, you will have the opportunity to add them to the campaign. Ultimately the total number of influencers involved (and the cost) depends on how many express interest and then how many of those you decide to include.
