Mr Rankin has written a brand new Rebus tale exclusively for the event on 4 March.
There will also be an opportunity to chat to the author about his life and inspirations, as well as an auction of special Rebus memorabilia.
Marketing and fundraising manager for Royal Blind, Helen Forrest, said: "This once in a lifetime opportunity is not to be missed for Rebus and Rankin fans. There should be a fantastic atmosphere as guests try to second guess the plot and find out more about Ian.
"We are really privileged to have this support from Ian Rankin."
