Book

Okay, so I've been searching for this book for a while and I need help finding it. These boys go on a trip to Paris I think and get partnered up together. I'm pretty sure it's a gay, boyxboy story but im not sure. I read it long time ago and I can't figure out what it's called, or how to find it so I've resorted to this. Making a book just to find another book. More info inside if I can think of it.
