A Darker Shade of Magic, by V.E. Schwab

This was an engaging YA fantasy set partly in late Victorian (or possibly Edwardian) London, and partly in two parallel Londons, each ruled by different kinds of magic. The main character, Kell, comes from “Red London,” the more stable of the two magical kingdoms, but is one of the few people with the ability to move between worlds. In “Grey London” (that is, the London in our world) he meets a young thief called Lila Bard, and their fates become intertwined as they try to head off a magical disaster that has its origin in the violent and unstable “White London” but threatens all the realms.

I found this enjoyable and engaging while i was reading it. It’s the first of a trilogy, and while I wasn’t so compelled that I had to immediately pick up the next book to find out what happens, I very likely will go ahead and read the whole series.
