Among the Ten Thousand Things by Julia Pierpont. The book is being released by Random House on July 7, 2015.
Amazon says this about the book: Jack Shanley is a well-known New York artist, charming and vain, who doesn’t mean to plunge his family into crisis. His wife, Deb, gladly left behind a difficult career as a dancer to raise the two children she adores. In the ensuing years, she has mostly avoided coming face-to-face with the weaknesses of the man she married. But then an anonymously sent package arrives in the mail: a cardboard box containing sheaves of printed emails chronicling Jack’s secret life. The package is addressed to Deb, but it’s delivered into the wrong hands: her children’s.
With this vertiginous opening begins a debut that is by turns funny, wise, and indescribably moving. As the Shanleys spin apart into separate orbits, leaving New York in an attempt to regain their bearings, fifteen-year-old Simon feels the allure of adult freedoms for the first time, while eleven-year-old Kay wanders precariously into a grown-up world she can’t possibly understand. Writing with extraordinary precision, humor, and beauty, Julia Pierpont has crafted a timeless, hugely enjoyable novel about the bonds of family life—their brittleness, and their resilience.
