Having read very little Star Wars fiction, yet being a fan of the series, I've decided after watching a Star Wars marathon of all of the movies that I'd start reading the novels to continue the story. Which book/series should I start with to continue the adventures of Luke Skywalker and company?
Now that the Star Wars expanded universe has been rebooted, the series that takes place right after Return of the Jedi in the new canon is the Aftermath trilogy. This is the one to read if you're looking for something that will be consistent with The Force Awakens.
According to Wikipedia, Kathy Tyers' The Truce at Bakura looks like the first book after Return of the Jedi chronologically.
That being said, I've always considered Timothy Zahn's Thrawn trilogy (starting with Heir to the Empire) to be my stand-in for episodes 7-9. The quality of those books in particular is quite high, and the narrative is largely about the same characters as in the movies.
There is also the book "Courtship of Princess Leia," which occurs after the Truce at Bakura and before the Thrawn Trilogy.
