The delight of listening to someone talk about something you have read and enjoyed but hadn't known anyone else had read. I had read HPMOR a while ago and hadn't realised it had finished (I think I stopped before the let the readers solve my characters challange) so thanks for reminding me about this fun tale. Yes please indeed do more of these.

Suggested books/series with a multiverse His Dark Materials by Philip Pullman, The Invisible Library by Genevieve Cogman, The Space Between Worlds by Micaiah Johnson to name a few.
