Original Adventures Reincarnated #3: Expedition to the Barrier Peaks (5e Adventure, Hardback)

Is this just the one module, or the whole s- series adventure?

Are the maps Blue like the original module or sre they black and white? I hated the blue maps. :-(

Is this both books or just one?

The book says this covers PC levels 8 - 12, is that accurate for the 5e version? How far can we take the adventure?
