The most popular Spanish space opera books of 2021

Space opera is science fiction on the grandest scale. Galactic empires rise and fall, fleets clash between the stars, and a ragtag crew usually ends up in the middle of it. Expect adventure, politics, romance and big emotions more than hard physics. Many of these stories run across long, absorbing series. This list shows the ones first published in 2021. Only books in Spanish are listed.
