If you absolutely refuse to give Amazon your email address, go with via your local library. It’s slower, but it is truly free—no strings attached.

Since its release, this novel—pitting Necron overlords Trazyn the Infinite (a museum curator with kleptomaniac tendencies) against Orikan the Diviner (a time-traveling cosmic accountant)—has become a fan favorite. The audiobook, narrated by the legendary Richard Reed, elevates the story to new heights, capturing the dry, millennia-spanning sarcasm of two immortal robots who hate each other’s guts.

It is no surprise, then, that the search query explodes across Google every single week.

It takes three minutes to sign up, you get a professional, studio-mastered experience, and you don’t risk a virus. Plus, you own the file. You can listen to Trazyn call Orikan a "calculator-obsessed fossil" while you drive to work, fold laundry, or paint your own Necron army.
