Waiting for the Galactic bus begins at the begining...of the human race that is. Some aliens who can exist in solid form or in energy are taking a trip around the universe, tripping all the way since they're young and want to try the latest and greatest in sensory experience through thier equivilant of drugs and extreme sports. They happen upon a planet where they spend some time drinking in the rich atmosphere and experiencing various solid forms, getting drunk on the sensations. When they're ready to leave, two brothers in thier number who are considered trouble makers and losers are too drunk and get left behind. The others decide they'll come back for them in an aeon or two, serves them right for being drunk jerks, right?
Barion and Coyul wake to find themselves alone, with nothing but the primitive life of Earth to keep them company. Since they're so bored, one decides to give self-awareness to a monkey and start a human species. His brother warns him against this, as there are serious laws against elevating species before they are prepared for it, the disasters resulting from such irresponsible advancement of a species are terrible and the punishments severe. But, since the deed's been done, might as well improve on the design, right? figures the other brother.
And so, it is the begining of all the creativity, sadness, hope, destruction, love, hate, art, and violence. Barion and Coyul soon discover that this new species just keeps going on after they die in the form of consious energy. Not quite sure what to do with them, they decide to throw them a party, and "Upstairs" and "Downstairs" develop, and religions on earth develop and influence the way the realms develop.
So, after witnessing human history, and all the violence it can produce, as well as recognising the potential, they decide to intervene to stop what could very well be the next Hitler, before he is even conceived. And here is where our human charachters enter. Charity and Roy...Roy the Nazi wanna-be, and Charity, who has great potential, but doesn't know much of anything outside what she learned in a podunk little town; poverty, the local tabernacle church, and McDonalds.
Coyul and Barion take them on a ride through downstairs they can never forget, giving them both thier individual dreams to wake the sleeping genious in Charity, and to show her the monster the Roy can become. Charachters throughout history are also working in the realms of upstairs and downstairs and add a lot to the story. All told in witty, thoughtfull, and downright funny prose. A very enjoyable read.
