In the Prologue, what does Gene share about his last graphic novel and starting a new one in the novel, Dragon Hoops?

Gene says that his last graphic novel was published in 2013. It took him six years to finish with teaching and family obligations. By the fall of 2014, he still did not have an idea for a new story. He worried that he did not have any stories left to write about. He started hearing about the basketball team, and he became intrigued.
