Every Anxious Wave

Imagine 11/22/63, except instead of traveling back in time to right the course of history, Karl Bender is going back to see his favorite bands perform live. Karl's mundane life becomes a lot more interesting when he discovers a portal to the past in his closest. He starts time traveling to see his favorite musicians, and selling others the opportunity to do the same. Of course it doesn't go according to plan. The concept alone makes this worth reading if you love punk rock and time travel. But the center goes all wobbly, and because the characters' visits to the past keep changing the future, the ending will make some of you crazy. (Remember the 8-line edit? Take note.)
