Once upon a time, when I was eleven years old, I read The Midnight Club. And Chain Letter, and its sequel. All of which were written by an author whose pseudonym is the name of that guy from Star Trek. But I digress.
Sati, by the same author, is a novel marketed towards adults, but to be honest I could have read it at the same time as the above-mentioned YA novels without too much difficulty. The premise is rather simple: God decides to play on Earth, in L.A. of all places, and took the form of a blonde, blue-eyed girl who calls herself Sati. She talks to some people, makes delicious cookies, borrows elements from Hinduism, reminds everyone that the whole point of life is to enjoy yourself and find your "inner silence", and then leaves. All of this is narrated by the guy who found her in the desert, brought her back to his apartment and skeptically watched while she proceeded to enlighten pretty much everyone around him.
That's it, really. I've left out the predictable twist! at the end of the novel, and the many and various subplots, but really, that's it. 217 pages of calm and spirituality and cherry cookies. It was okay.
