...what would it be about? Something I've been pondering a bit lately now that Disney and Lucas Film are getting novels and books out more consistently.
Seeing how that we're getting Last Shot as a set of three different stories exploring the Han/Lando relationship both before Solo, after Solo and shortly after the Aftermath Trilogy ends, I would be inspired to do something similar with what I dub Star Wars: Children of the Sands. Basically it would be a set of three novellas focusing on Anakin, Luke and Rey as children... three different would-be heroes who share in common the difficulty of growing up on the harsh, unforgiving worlds of Tattoine and Jakku, and allowing canon and a writer (or three) to flesh out a moment in their early years.
Anakin's tale could resolve around his discovery of C-3PO and his drive to becoming a Pod Racer and the start of his rivalry with Sebula whilst Watto and Shimi watch over him in different ways. Luke's story would be about becoming friends with Briggs, his pilot skills and first trip to the canyon whilst the Lars remain very protective. And finally Rey's story would show how she struggles to cope without the parents she cannot recall as she picks up the skills to survive on Niima Outpost with the aggressive Unkar Plutt keeping an eye on her. Basically three stories showing the similarities and differences those three heroes to be of three different eras have. I think it would make for a nice read, something like that.
