Language in Leviathan Wakes (The Expanse, #1)

While there are no specific slurs against real-world protected groups, there is a recurring use of derogatory slang for…

Heavy themes of corporate greed, political manipulation, and the ethics of human experimentation.

Miller's character arc focuses on obsession, loss, and the nihilism of a man who has lost his place in society. The narrative also grapples with the concept of the 'uncanny valley' through the protomolecule, questioning what defines humanity when biology is repurposed by alien technology. The…
