THE BOTTOM LINE: Fascinating characters abound, but unfortunately they have little to do.
WHEN TYLER JOHNSON'S MOTHER wakes up one morning to find the word divorce printed on her forehead in black felt pen, the reader can't help tingling with anticipation that more fun awaits. And for a while Douglas Coupland delivers, drawing delectable characters such as narrator Tyler with his Smithsonian- class collection of shampoos; his sister Daisy, a neohippie in blond dreadlocks; and his mother Jasmine, a twice-divorced hippie with the felt- penned forehead.
The book thrives...
