Odo Valsecca, a promising nobleman, inherits a dukedom at a young age and, over the course of his young life, must quickly learn the politics of royalty as he deals with other nobles, the church, the free-thinking movement, and, of course, his subjects, the peasants. Will he be able to rise to power in time, or will he quickly buckle under the pressures of the Italian court during the seventeenth century? Published in 1902, The Valley of Decision is Edith Wharton's first full length novel. - Summary by Mary Kay
