Twelve-year-old Dani is running away from home, or what’s left of home anyway. Her older brother, who had muscular dystrophy, died a few months ago. Then her father left and her parents got divorced. Now home is just Dani and her sad, silent mother, and Dani’s got to get away. She plans to do something amazing, and go where her parents will never find her: she’s going to hike the whole Appalachian Trail, from Georgia to Maine. The trail is a legend in her family, the place where her parents met, fell in love, and got married 14 years before.

Unfortunately for her master plan, her mother doesn’t have much trouble figuring out where Dani’s gone. Now it’s the two of them, hiking for as long as Dani can manage to persuade her mother to keep going. But Dani’s got an even longer emotional journey to make—and it’s one she and her mom need to make together.

Suddenly, Father is not only a famous cowboy, war hero, and politician, but also President Theodore Roosevelt, leader of the United States—and Ethel has a new place to call home. The White House is older and stuffier than Ethel imagined, but there’s never a dull moment with her adventurous family around. Ethel would love to spend every day following Father on horseback rides and scrambles through neighboring Rock Creek Park.

Instead, Ethel has to stay at boarding school during the week, where nothing she does feels right and none of the girls seem to like her. Ethel’s parents keep telling her to keep her chin up and be patient, but it’s not easy being the president’s daughter. Ethel wishes she could be as courageous as father and make her family proud. When her fashionable older sister arrives home, Ethel feels new hope. Sister knows the secret of being brave and making friends, and she’s willing to share it. All Ethel needs to do is take one outrageous dare.

Abigail is starting a new middle school, a Catholic school, because she’s been expelled from her old one. She’s sure that this place will be just the same as the last, and no one will listen to her here either. Even her parents don’t seem able to really hear the truth about what happened at the previous school. But now she finds herself in a community of people who do listen, who want to be her friends, and who help her discover a talent for theater that she never knew she had. Converting to Catholicism began merely as a way to annoy her parents, but quickly it becomes more. Could she be developing real faith?

Kimberly Brubaker Bradley masterfully tells the tale of Abigail’s spiritual journey and the faith that comes to those who need it....
