Lemonade Mouth (made into a Disney Channel movie - no, I did not see it). It has been a long time since I read the first one, and I had forgotten much of the story. I remembered liking the tale of some high school students who make an unlikely music group. I know there was something about a protest involving drinks allowed in school, too.
We pick up the group's story as the band members (and others involved) recount the eventful summer after the previous book. The band is made up of some unusual instruments (trumpet and ukelele, to name two). Following a local concert, the group is approached by the manager of several successful rock performers and are told he wants to make them superstars. It's a rocky road for our group who are new to the world of big time entertainment. As much as they want to be successful and have their music heard, they do not always agree with the decisions made for their career. Being true to themselves is important, so they are often at odds with what they are being asked to do.
In addition to all the band activities, the members are also dealing with typical teen issues: relationships, parents, summer jobs. Generally, the issues are not too serious (compared to other teen books). These young people are always striving to do the right thing and stand up for what they believe. It is nice to read a book that is lighter in tone and does not get graphic and too serious.
If you are going to read this, you should start with the first one.
