To Touch the Stars — Pamela Browning

In Peaceable Kingdom, Georgia, people were walking on air

Julie Andrassy watched in distress as her relatives succumbed to the family madness, taking to the sky, as their feet remembered how to master the thin wire. Most triumphant was Stephen Martinovic, the dashing emigre who'd resurrected the reckless dream of reuniting the Amazing Andrassys, the most daring family ever to walk the high wire.

Julie alone remained safely earthbound, refusing to reach for the stars. For if she did, she would have to admit that Stephen and the high wire were twin fires in her blood.
