Looking for Mecha Books (Like Battletech, etc.)

I’m looking for recommendations of books about mechas — in other words, about robots controlled by people, and usually shown in battles. That is, books like Mobile Suit Gundam, BattleTech, Robotech, Titanicus, etc.

There are a lot of books based on those shows and games — and it’s hard to navigate the field. (*metallic stomp stomp stomp*) So I’d love suggestions about which books to try.

Also, I’d love to find books inspired by mechas — but using their own worlds and settings. Can anyone recommend something in this vein. I’ve seen quite a few indie SF books in this field.
:thanks:
