CRUSADER by Edward Bloor is set largely at a virtual reality arcade in a dying mall. It's more about the issues surrounding the violence and racism in some of the VR games that mirrors the local reality, than it is about the VR worlds themselves.

HEIR APPARENT by Vivian Vande Velde  is a kind of "Groundhog Day" live-the-day-over-again-till-you-get-it-right tale, wherein a girl gets stuck in a life-or-death virtual reality game when anti-VR protesting parents mess up the arcade circuitry. There's a lot of humor in this one.
