Query: Orchid Fever

"In my 40 years as an orchid scientist, author and book editor, I have never read anything quite like ORCHID FEVER. It is part absurdist black humor and part horticultural expose. Mr. Hansen displays a rare talent for capturing the allure of orchids, describing the dubious characters who lurk in the shadows, and exposing the small handful of self-appointed power brokers who rule the orchid world. Frightening, funny and full of tantalizing insider knowledge. And yes...there are strange and wonderful stories about orchids as well. I have a distinct feeling that what was left unsaid about several people is much more interesting than what was written. I look forward to a no holds barred second edition."Dr. Joseph Arditti Editor, Orchid Biology Irvine
