It may not really come as a surprise that this book is like a modern retelling of the story of Orpheus and Euridice. Although in this book, 'Orpheus' gets lost (the title is already spoiling it, really).
Mishka is a musician, and ironically plays a piece of music about Orpheus on multiple occasions. He's also looking for his Lebanese father, which brings him into a world of terrorism. His girlfriend sets out to find him and bring him back. Sounds familiar huh?
The book has a lot of different setting, America (multiple places), Middle East and Australia. The switching between the places/times got me a bit out of the flow of the book. The story itself was quite interesting and I did like the writing, although it was at times a bit slow.
Note: I read a Dutch translation of this book
