The Shades of Magic Universe

The shared-world umbrella for V.E. Schwab's Shades of Magic universe: the world of four parallel Londons — Red, Grey, White and, once, Black. It gathers the completed "Shades of Magic" trilogy, the "Threads of Power" sequel series (ongoing), and the "Shades of Magic: The Steel Prince" prequel comics, which Schwab has described as bridging the two prose series.
