Exclusive: Walker Books shares new UK cover artwork for City of Glass on #TMIBlogTour (+ UK Giveaway)

Welcome to Day 3 of the #TMIblogtour hosted by Walker Books! We are so very honored to be able to share with you images of the new UK cover designs of The Mortal Instruments series. Yesterday, Mundie Moms shared the new City of Glass cover, and each day for the rest of this week you can see a new cover on one of the lucky Shadowhunter blog sites selected to host.


To celebrate the publication of these stunning new editions of TMI, out in the UK this week, we at The Mortal Institute have teamed up with Walker Books for a blog tour to show the amazing artwork created for these covers.

Here’s the piece of art used for City of Glass, and the cover – click on the art to see the intricate detail of it!



The artwork was created by Míla Fürstová, an award-winning internationally exhibited artist, who has shown in 20 solo shows in many countries, including Britain, USA, France and the Czech Republic over the last decade. During this time she has won 14 prestigious awards. Her work has become part of important private and public collections, including that of Queen Elizabeth II and the V&A Museum in London and has featured in numerous publications. She also designed the illustration for the CD cover of Coldplay’s Ghost Stories, a big reason why Walker Books commissioned her for these new covers.


Míla uses a print-making medium from the Middle Ages called etching:

  • She uses a metal plate coated with wax
  • She draws the illustration with a metal needle, exposing the bare metal
  • The plate is then immersed in acid and the acid bites into the metal, where it’s exposed, resulting in lines on the plate
  • The plate is inked all over, and the ink goes into the lines
  •  The plate is put through a high-pressure printing press together with a sheet of paper and the paper picks up the ink from the etched lines, making a print

Using this method, she made an intricate etching for each book, drawing on a metal plate. This was then used to produce the print featured above, which we then digitally coloured to use on the cover.

The choice of illustration for each cover was the result of a conversation between the Walker Books designer, Maria, and Míla. Everything had to be approved at sketch stage, because once the illustration is drawn onto the plate it’s very difficult to modify.

So for each piece of art, Maria sent Míla a full cover briefing of 5/6 pages per book with a synopsis, symbols, objects and extracts from the books with descriptions of characters, scenes and locations.

The briefing also suggested a few ways that Míla could go with the piece for the book.

Below is a snippet of the illustration briefing for City of Glass.

Angel Raziel could be the main character. He could be rising from Lake Lyn. He is summoned by Valentine in this book.

Alicante and the demon towers are nice backgrounds to illustrate. The demon towers could have some demons around, illustrating the moment when the wards go down.

There’s a big fight between Shadowhunters and Downworlders (these two working together) against demons. Some silhouettes in the background could be added.

Magnus Bane could be in the background as well, holding a flame with one of his hands. He is an interesting character to illustrate and all the fans love him! He also plays a big part in this book.

One of the objects could be the mortal sword, as it’s an important instrument in this book that allows Valentine to create an army of demons.

Míla first sent in sketches with her initial thoughts.


Then there would be a bit of conversation about the sketch, before she produced the final etching on the metal plate to make the print with. Below is an example that shows the process.


Here is the final etched plate for City of Glass.
