Jon isn't sure about his move, but he feels he needs to be. He quit his band after finishing college (they're now becoming an indie sensation, which puts some urgency into his choice to succeed at something other than music), and now he's not sure what his life is for or what it will come to.
When Jon meets Koko (she steals his tape recorder after a raucous performance at the Zeitgeist in the Mission), he finds himself subject to her withering scorn and tough questions. But the interrogation isn't one-way -- in the process of criticizing Jon's do-gooder ambitions, Koko comes to realize how empty her own life is.
The two of them enter into a struggle to find meaning and happiness -- to be "good" -- and embark on a difficult journey that involves a huge cast of minor characters all engaged in their own existential battles.
All the above makes the book sound moody and brooding, but it's anything but. Koko Be Good brims with manic energy and comedy, a complex story engagingly told with ingenious layouts and lovely art.
