I picked up both books of the Capellan Solution for my kid. Wondering if anyone has read these... They look like the usual "not groundbreaking literature but entertaining" kind of fare. Anything they should read before hand?

I'm also curious, I noticed there are a lot of books that sit in chronological order but don't seem to be part of series. I assume most of them can be read out of order? It's been a bit over twenty-five years since I read a BT book myself.
