The 1st chapter, the longest, begins the tale of first love between two 17 year old boys in 1984. The 2nd chapter jumps to 2007 and the 3rd chapter to 2016.
Unfortunately, the beginning of the book, the recounting of the youthful relationship, didn't work for me as much as I would have liked. The narrator's voice kept me at arms length and I had a great deal of difficulty connecting. Not to say that the prose isn't exquisite in places thanks to Molly Ringwalds translation (since I can't read the original French) but the telling was, for me, cold and aloof. Interestingly this was not the case in the 2nd and 3rd parts.
