Reddit reviews Down with the Queen (Lilith's Shadow Book 2)

I'd like to add the works of Benjamin Mandrano to that list:

• Ancient Dreams is a Dungeon Core series with an interesting twist (and heads and shoulders above the other Dungeon Core works out there)
  
• Born a Queen and Down with the Queen are superhero novels about Lilith, the originally spare body of a notorious supervillain now conscious
  
  Also, I see you have A Thousand Li by Tao Wong, but it seems you forgot his System Apocalypse series! It's an awesome lit-rpg series about what happens when everyone on Earth gets a video-game-like Interface, full with stats, classes, and skills - and then monsters keep spawning everywhere.
