I am reading an ebook I found on goodreads of a continuation of the Harry Potter series that follows his son James. James Potter and the Hall of Elders' Crossing by G. Norman Lippert, is the first in the series of 4. There also seemed to be several side short stories. Kinda makes me want to read Harry Potter all over again. So check it out if you've got the time and we can discuss it over coffee.
