Can anyone recommend introductory
books on the subject?

The book "To Rise from Earth: An Easy to Understand
Guide to Space Flight" by Wayne Lee (a mission planner
at NASA) could serve as a good introduction. Very easy
to read and nicely illustrated.

Chapter 2 is "Above the Clouds: Orbital Mechanics
Without Math", and Chapter 3 is "Dancing in the Dark:
How to Perform Space Maneuvers."

Amazon.com carries the book, and your local library might
even have a copy.
