One of our best-loved writers, author of the phenomenal bestsellers The Bridge Across Forever, One, Running from Safety, and Jonathan Livingston Seagull, returns with a brilliantly conceived narrative about the nature of creativity. Bach's journey begins as he puzzles over design modifications for his airplane, a Piper Cub. Perfect designs--simple and practical--seem to come to him out of the blue. But one day when a design appears, along with a fleeting glimpse of an intriguing woman, Bach sets out to discover the source of the visions. The journey leads to a startling destination: a parallel universe where a British airplane manufacturer--Saunders-Vixen Aircraft Company Ltd.--makes superb biplanes and solves problems for perplexed aviators. There Bach meets Derek Hawthorne, his guide through Saunders-Vixen and the new world whose possibilities are just unfolding. There Bach also meets his muse, an unforgettable young aircraft designer named Laura Bristol, who teaches Bach the beauty of simplicity and practicality.
