I'm a science fiction 'virgin' and really wasn't looking forward to reading this book. But boy, am I glad I did. Original plot and easy to read, I romped through in days. I found it a frightening experience, not frightening in the sense of BOO!, but one which leaves you quietly unsettled. I don't think I'll look forward to going to bed next time it's a windy night - you never know what you'll wake up to or with whom!
