Steve has little to do with Lisa and her mother (who he never married) in the beginning, and only acknowledges paternity under duress. Eventually, he has a relationship with Lisa, albeit an unusual one. They skate together, have dinner together and in high school Lisa even lives with Steve and his wife and son. But it's a relationship fraught with uncertainty and even meanness. Steve won't admit he named his Lisa computer after his daughter. He belittles Lisa and refuses to pay for her last year of college. Lisa has the final word, though, in the way of all memorable memoirists.
What I liked best about Lisa's writing was when she described the California of her youth, the sights and smells of the land she came alive to: "Here the soil was black and wet and fragrant; beneath rocks I discovered small red bugs, pink- and ash-colored worms, thin centipedes, and slate-colored woodlice that curled into armored spheres when I bothered them. The air smelled of eucalyptus and sunshine-warmed dirt, moisture, cut grass."
It reminds me of George Eliot's line: "We would never have loved the earth so well if we had had no childhood in it."
