Looking for a book with the same energy as Industry or Succession — ensemble cast, high stakes, plenty of backstabbing

I’m searching for a book that gives me the same rush I get when I watch shows like Industry or Succession. Something with a fast-paced plot, a large ensemble cast, and lots of drama involving problematic characters, backstabbing, power struggles, and high-stakes business dealings. Any recommendations for novels that hit that same vibe of corporate tension, complicated relationships, and morally grey characters? Would love a gripping read that keeps me hooked!
