Forever Fantasy Online (FFO Book 1)

Details: In the real world, twenty-one-year-old library sciences student Tina Anderson is invisible and under-appreciated, but in the VR-game Forever Fantasy Online, she's Roxxy—the respected leader and main tank of a top-tier raiding guild. Her brother, James Anderson, has a similar problem. IRL he’s a college dropout struggling with debt, but in FFO he's famous.
