The Republic of Heaven

I really want to see a full novel of after the times, just to find out how various characters adapted to relatively normal life. Ofcourse I'm dieing for Lyra and Will to get together in my heart but I know it won't happen.I'd like to know what happened to Lyra and Will, whether they were happy but honestly I'd just like another story. Please Mr Pullman, tell us stories, but make sure they are true!
