What is the main conflict in Criss Cross by Lynne Rae Perkins?

It is spring in Seldem, a small town that could be anywhere in the U.S., and Debbie is looking forward to her summer vacation, though she wishes that something good would happen to her. In Seldem, very little exciting happens, and this summer will probably be no different. As school comes to an end, she begins to hang out with her normal friends, Patty, Hector, Lenny and Phil, doing normal things - walking around town, going to the Tastee Freez, and sitting in Lenny's dad's parked truck each evening listening to the nightly "Criss Cross" radio show. Hector is feeling the same way as Debbie and, after hearing a guitarist play at a local coffee house, takes a bit of action, in the form of guitar lessons at a local church.
