Book excerpt: Survival Strategy #50: If You Can, Be Brave It's easy to be brave when your eight-year-old sister, Billie, looks up to you as her protector. Twelve-year-old Liberty feels it's her job to look after Billie once they are sent to live with their father, whom they haven't seen since they were very young. Dad is unpredictable on his best days, but when he abandons the girls at a gas station in the middle of nowhere, Liberty's courage is truly put to the test. As she and Billie struggle to make it home on their own, they encounter a cast of both helpful and not-so-helpful characters, including a man with caterpillar eyebrows, a lady dressed entirely in lavender, a tattooed trucker with a soft spot for cats, a kid who is a little too obsessed with Star Wars, and a woman who lives with a houseful of nontraditional pets. Along the way, they learn that sometimes you have to get a little bit lost to be found.
