I’m not going to read what has been posted already to see if there are any dupes, but here goes:
Pillars of the Earth by Ken Follett
Soldier of the Great War by Mark Helprin
THUD! by Terry Pratchett
Sarum by Edward Rutherford
Mere Christianity by CS Lewis
Day of the Jackal by Fredrick Forsyth
Only Pillars and Sarum are roughly the same genre.
Without looking back I think only Pillars of the Earth was said. Thank you for those interesting sounding choices, I know I will enjoy them!
