It's an older book but I personally love it. It's full of knights, horses, kings, captives, castles, and adventure in general! The authers name is John White.

Fyi this cover is really old so they changed it by now.

And this is an illustration in the book!
Looks and sounds cool! I'll have to look into reading it
You'll enjoy it!
This looks really interesting!!!
That does look interesting
Actually, the first book in this totally amazing series is called "The Sword Bearer". I made a teeny mistake.
Wow, looks cool, I'll try to read it when I have the time!
