After the Wallpaper Music, by Jean Mills

Flora and her three friends are the Arden String Quartet, a talented group of middle schoolers.  They are always getting asked to perform at school functions (parents nights, etc.) -- the veritable "wallpaper music" group.  So, when the school announces a Battle of the Bands, the Quartet will of course play a piece.  But they struggle to decide what they should play.  Flora wants to play a traditional classical quartet while the other want to play music from a video game.  They settle that dispute amicably, but when Flora gets asked by a new boy to play in his band as well, jealousies appear and Flora is faced with conflicting loyalties that are harder to resolve.

Alongside that drama, Flora's aunt who lives with them has a health scare and Flora has to face the fact that people get older and people get sick.  From this she learns the healing power of music in giving people a means to come together and enjoy each other in the face of adversity.

A mixture of themes that ultimately tackles the topic of loss and grief rather more successfully than the interpersonal conflicts that Flora must contend with.  I liked the various different ways that music is brought up in the story, ranging from its role in cultural identity to the effects of fame for those who make it big.  In the face of all the different ideas brought up in the story, the lack of a nice neat ending felt right.
