Purple has a difficult job: He was placed here to take down the One-Eyed God. It's his mission and he won't fail. It's a lonely road for someone like him-a healer-but he has help. The hippies are his friends: Chloe the yogi, Wheat the candlestick maker, and Berrydream, who is in retail. And he has his tribe: Charlotte, Stranger and Jackson. Eventually, the tigers that roam the city might become allies, too. Who can say, tigers are fickle.
The One-Eyed God is nefarious and powerful. His agents lurk everywhere and the aliens are certainly up to no good. The government is clearly working with the aliens to force the Second Coming-and that will only lead to tragedy. Even the one called Sister can't be trusted.
But the universe is wise and has given Purple skills. Getting control of his invisibility will help, but that only matters as long as molecular cohesion is maintained. Most of all, Purple has purpose and, of course, he has his broom.
