Seglin, S. (April 2007). Wahl, Mats. The Invisible.(Young adult review)(Brief article)(Book review). School Library Journal, 53, 4. p.150(1).

As Hilmer walks through his school, he realizes that there is something terribly wrong with him; he has become invisible! No one can hear him, no one can see him. What's worse is that Hilmer is starting to forget that night - the one where he was murdered. Desperate to find answers about his own murder, Hilmer follows detective Fors, who is the leading investigator in the crime.
We see most of the story through Fors's point of view as he investigates and uncovers clues about Hilmer's death. Mats Wahl is a real master at the little details that bring characters or situations to life. The dialog is realistic and forward. The only reason I'm not giving this book 5 stars is that the ending was pretty predictable and there was no real twist. But I highly recommend this book if you enjoy detective stories and thrillers on the creepy side. ( )

A Swedish teen has gone missing, and a local detective is determined to find out what happened to him. The boy's spirit, follows him, trying to understand what has happened. ( )

Hilmer walked into school on Monday morning like normal, but quickly discovers that this isn't going to be a normal day. No one can see him. No one can hear him. Hilmer is invisible. Being invisible is a big enough problem on its own, but what makes it worse for Hilmer is the fact that he has no idea why he is invisible.It doesn't take long for Hilmer to find out that everyone thinks he has disappeared and that many people suspect foul play.Detective For is in charge of Hilmer's disappearance case. Hilmer decides if he stays close to him, he'll find out what happened and where his body is. Detective For hits many obstacles while trying to figure out what happened on the last day Hilmer was seen. Several local officials encourage Detective For to consider Hilmer a runaway and to not look too deeply into the mystery because it might look bad for the community. The community leaders are hoping the town will become a tourist/vacation spot. Turning up anything negative will bring in the press and possibly turn potential visitors away.Getting anyone to talk about what is going on in the school is difficult. Detective For can clearly see that Hilmer's locker has been recently painted in order to cover up graffiti. The word "Traitor" is scrawled on top of the new paint job, giving the detective a place to start. He finds out that there have been altercations between many of the locals and the immigrants moving in from other countries. After questioning students and teachers, Detective For learns that Hilmer defended one of the immigrants shortly before his disappearance.Issues of prejudice, white power, immigration, and hatred surface during the investigation. Can Detective For put together all the clues in time to help Hilmer become visible again?THE INVISIBLE by Mats Wahl is now a major motion picture; however, after reading a synopsis of the movie, so much has been changed that it doesn't resemble the premise of the book. It would be fair to say that the movie is LOOSELY based on the book of the same name. ( )

Translated by Katarina Tucker. Takes place in Sweden.
The whole novel takes place over two days. On a Monday morning Hilmer Eriksson is sitting at school only to realize he's invisible to everyone. Everyone else is talking about how he has not been seen since Saturday. The story is told through his eyes as he watched the detective assigned to locate him. A fast read with an interesting tone. ( )
