Science fiction has always been an escapist’s dream, rooted in science, fiction, and fantasy, all rolled into one. One of the earliest and possibly most popular subgenres in sci-fi is the space opera, which usually tosses the laws of sci-fi out of the window and embraces fantastical entertainment.

Space opera, if you’re not familiar, is a subgenre of sci-fi that combines fictional space warfare, melodrama, chivalric romance, and amazing adventures all set upon a vast, intergalactic stage. Early proto-space opera began as early as the late 1800s, but it wasn’t until the 1920s that space opera as a subgenre really took off, gaining popularity in pulp magazines like Amazing Stories.

If you love swashbuckling adventures that take place in outer space, we’ve got some of the best books to read online for free! Keep reading to discover some cosmic space opera reads from both past and present.

A Princess of Mars by Edgar Rice Burroughs (earliest space opera style)

Confederate Captain John Carter heads to Arizona after the Civil War ends with his friend and fellow soldier James Powell. When James is killed by a Native American tribe, John seeks refuge in a cave. But when a strange, noxious gas knocks him out, he wakes up—on Mars. Because of the low gravity on Mars, John appears to have extreme strength and agility, making him an instant hit with the Martians. John becomes part of their tribe and helps them attack a warring tribe. When the Martians kidnap human princess Dejah, and he discovers Dejah will be killed, he rushes in to save the day.

Although he is remembered most for his Tarzan series of books, Burroughs also published groundbreaking science fiction in the early 1900s, his Barsoom series being the most popular. Published in 1912, A Princess of Mars (the first of the Barsoom books) is considered one of the earliest space opera style novels.
