Book excerpt: Printz Honor Book • YALSA Nonfiction Award Winner • Boston Globe-Horn Book Award Winner • SCBWI Golden Kite Winner • Cybils Senior High Nonfiction Award Winner From the author of National Book Award finalist Charles and Emma comes an incredible story of brotherly love. The deep and enduring friendship between Vincent and Theo Van Gogh shaped both brothers' lives. Confidant, champion, sympathizer, friend—Theo supported Vincent as he struggled to find his path in life. They shared everything, swapping stories of lovers and friends, successes and disappointments, dreams and ambitions. Meticulously researched, drawing on the 658 letters Vincent wrote to Theo during his lifetime, Deborah Heiligman weaves a tale of two lives intertwined and the extraordinary love of the Van Gogh brothers.
