On the eve of the American Revolution, as war approaches, Sarah Revere's father, Paul, is often away from home as he rides from town to town warning the militias about British troop movements and deployment in the region. Close family friend Dr. Joseph Warren watches over the large Revere household, but Sarah suspects that his interest in her attractive stepmother, Rachel, is more than friendly. She confronts him, but Dr. Warren is so hurt and angered by Sarah's suspicions that a rift is created. When the doctor goes into battle Sarah realizes that she may have misjudged him and cries out for forgiveness, never certain that he granted it. After determining that her actions were just a cover for her own unseemly feelings for him, Sarah is devastated by what she has done, and even more devastated by news of the doctor's death in battle. As usual, Rinaldi (Finishing Becca, 1994, etc.) has done her homework; the book is solidly researched and extremely well written. Readers will not soon forget these characters, whose actions and passions illuminate and enliven a historical era about which they may have heard much, but understood little. Vivid in the best sense of the word. (Fiction. 12+)
