If you're into it, the new Star Wars canon novels are very good!! There's some surrounding every movie, and around a lot of smaller characters. There's some geared towards YA readers that are really good, but have less subtext/complex plot. The audiobooks are also very well done.

Foundryside isn't technically a sci-fi, but like a steampun fantasy with a science-based "magic" system? It's a trilogy and very good so far.
