Guy Erma and the Son of Empire, by Sally Ann Melia

Second paragraph of third chapter:

He paused to look up at St Joseph’s Cathedral, said to be the beating heart of the Dome. At the top of the entrance stairs, there was a massive door where a bishop and head teacher waited for him.

Bought this back in 2015 because it was being hyped relentlessly by the author; took until now to read it; bounced off the leaden prose and won’t finish. You can get it here.

This was both my top unread book acquired in 2015 and the SF book that had lingered longest unread on my shelves. Next on both of those piles is Jocasta, by Brian Aldiss.
