A Darker Shade of Magic by V.E. Schwab
The beginning was weird and slow, but when I really got into the book, it turned out to be such an amazing story with great characters and unbelievable world(s). All these Londons were so different. I actually had a dream about the White one ... more like a nightmare, to be honest.
Kell, a wizard who can travel between worlds, is doing something illegal - for a price he smuggles things from one London to another. Delivering a letter to a dying man he has a feeling that something is wrong, so he opens the letter and finds a blank page. But the package with his payment contains a stone with very powerful and dangerous magic. Kell knows that such magic can destroy his world, so he tries to return it to its rightful place. While escaping the men trying to take to stone away, he meets Lila Bard, a pickpocket from Grey London, who is in search of her big adventure.
These characters were so amazing. I liked how conflicted Kell was - he seemed to have everything but actually was lonely and lost. And I adored Lila. She was wonderful - spunky and bloodthirsty but also brutally honest. Her friendship with Kell was a thing of beauty, so fragile and so strong at the same time.
I'm glad I got the book from the library and decided to finish it. Yes, there was a moment somewhere on page 30, I actually thought of dnf-ing the book (I told you the beginning was weird).
Now, I just have to wait for the second book to be translated into my mother tongue.
