Ice Planet Barbarians books in order

Reading order

The Ice Planet Barbarians series by Ruby Dixon follows a group of human women who are abducted by aliens and crash-land on a frozen planet inhabited by the sa-khui, large blue-skinned alien hunters. Each book pairs a different human woman with a sa-khui male through the “resonance” of the khui, a symbiotic organism that both species carry in their chests. The khui chooses mates by vibrating when compatible partners are near, creating an involuntary physical bond that the characters must then sort out emotionally.

What started as a self-published alien romance in 2015 grew into a cultural phenomenon after going viral on BookTok in 2021. The series spans 35 books, including full-length novels and shorter holiday novellas. The core appeal lies in the fish-out-of-water dynamic as modern human women adapt to a harsh alien world, and in watching both humans and aliens learn from each other. Dixon balances humor with genuine emotional stakes, and each couple faces distinct challenges while the larger community on the ice planet continues to grow and evolve around them.
