In 2016 he illustrated the word-free book Loose Screw, books that aim for the target group that ought to be able to read, but needs a reading experience that motivates and inspires them – and does not exclude them from the literary universe. He has also made, together with Magnus Holm, the critically acclaimed book about large numbers, Googolplex (2017). Markhus has received several awards for the books he has illustrated, amongst other things making a considerable mark of himself in the Year’s Most Beautiful Book Awards.
