There is a bundle of Sci-fi books available at StoryBundle, curated by Silvia Moreno-Garcia, author of Certain Dark Things and Signal to Noise, among others.
Many of the authors of the books available have appeared in the Latin@ Rising anthology and/or on Somos en escrito. David Bowles, author of They Call Me Güero (selected for the 2019 Tomás Rivera Mexican American Children’s Book Award) and Feathered Serpent, Dark Heart of Sky: Myths of Mexico (excerpted here on Somos en escrito), has his book, Lords of the Earth, available in the bundle.
If you ever want to get into homegrown Latino Sci-fi, the portal has opened, the alien tentacles are reaching out. Here at Somos en escrito, we can't recommend these books enough. These are the names to read in Latino Sci-Fi.
