In general I would say there's no good single book or resource that describes everything comprehensively. There's a lot of resources, though, but mostly scattered in various places.
The BEAM Book [1] is a good, though unfinished resource talking in general about the implementation - the memory model and the interpreter.
If you're interested in some very low-level details of the runtime, the internal documentation [2] also holds a lot of interesting details.
There are also some additional details on internals at Spawned Shelter [3].
