This book is a ride, no joke. You follow a constantly moving beam of light, "bouncing" off reflective surfaces (the light goes straight, with the world reflecting around it) among people around a soccer scandal. It's like a film noir in comic book style.
This book was originally published in French, then was translated into English, German, Spanish, and many other languages. I mention this because I read the English version first, then the French, and the English has several glaring issues. First off, it takes a name that was originally an anagram and changes it, but doesn't change any of the other names... So the English version flat out renders one of the book's puzzles unsolvable. Secondly, it actually leaves a couple French panels in untranslated, which (to me anyway) isn't a big deal, but doesn't look good on Delcourt. Thirdly, a couple parts that were translated to English have spelling errors and even just repeat the same lines over several times.
To get the best experience from this book, I'd suggest the original French version. The French is much cleaner and smoother to read, and gives a better idea of the situation at hand. One of the features behind this book is the digital version. Every physical copy includes a password for the website to access the digital version but my English version's website didn't work... The dev console had a whole host of errors. I don't know about the French version's site but wouldn't be surprised if it was also broken. (Note: this is the actual site, not the password. I couldn't even load the site to input a password)
One issue I do have is the price of this book. I bought it secondhand but I saw many copies through booksellers selling at $40+. I rarely comment on the price of literary books (especially visual ones) but given the weak translation and broken website, I cannot recommend this book for that price. If you're interested, find it secondhand (got mine from a German seller ironically) or check out a salvaged digital version on YouTube to help you decide if you want it.
