Excellent story, I especially enjoyed the music elements, how two stressed-out kids connect through music. There was a bit of a deus-ex-machina resolution at the end, but it fit. I really enjoyed this book. It even has song charts at the end for the songs Tripp and Lyla write together. However, I hope there are recordings of the songs somewhere, because chord progressions don't show the melody. You need a lead sheet for that, or to hear it... Lead sheets can have the chords too, but since they're written on a staff, they take more room & effort to print.

Es war so im Mittelmaß :)
