'Lisa' is the first book in the series of three
Lisa is a girl with a quite well-developed extra-sensory power - she can levitate herself. Not to put too fine a point on it, she can fly. Thinking herself more or less unique, she is amazed to find another girl with the same power - Jody. Needless to say, they quickly become friends - best friends. Together they develop their ESP powers, discoving telepathy, telekinesis and others. This leads them into several adventures, and to finding a third member of their group - Holly. The three girls form a small band of problem solvers, helping the armed forces and others. This has them travelling the world and being shot at - among other things.
This is her story, from her point of view.
Here's the actual book.
