One of the best books I've read on Virtual Reality topic is "Virtual Reality: Concepts and Technologies" (added among links below). It summarizes many VR aspects and it gives a good overview of Virtual Reality topic and its sub-topics.

Indeed, VR is a vast field composed by many sub-fields among which Software Architecture, Software Engineering, 3D Math, 3D Modelling, Computer Graphics algorithms and Tracking Systems and Real-Time rendering. Do you need something in a specific sub-domain?
