In 2016 I worked togheter with Amazon publishing and illustrated Jules Verne's classic "Journey to the Centre of the Earth". The Kindle book was released earlier in 2017 and was my first time illustrating a whole book. Quite a challenge but had a great time doing it. The Amazon team then applied subtle animations to some of the illustrations which brought them to life in a nice way. If your'e interested you can find it on Amazon.com by searching for "Kilian Eng Journey to the centre of the earth". Here are a couple of the illustrations. Its available to read for tablets and phones with the Kindle app for iOS & Android.
