Reddit reviews Shadowrun 17: House of the Sun

While I wholly agree that Nigel Findely is the gold standard for Shadowrun novels, I'd say that Lone Wolf was better than 2XS, although all of his novels, including the 2XS sequel House of the Sun, are excellent.

In terms of introducing/exploring the setting though, I'd say that Changeling by Chris Kubasik is the best. It's the story of a corporate kid who goblinizes into a troll, realizes his father no longer respects him, and runs away from home, eventually being forced into the shadows to survive.
