After their mother dies, Liberty and her little sister are reunited with their father, who left them when Liberty was a preschooler. When he abandons them at a truck stop in the middle of the desert, Liberty knows that it's up to her to take care of her sister and get the two of them to safety. Liberty loves to learn about the ways animals adapt in order to survive. Maybe she will find some survival strategies of her own.

This is a good, solid read. The two sisters are believable characters and the setting is also strong. The episodic plot is fast-paced. Readers who enjoy books like Homecoming and Waiting for Normal should take a look at this one. ( )
