From rising star Jessica Goodman, author of They Wish They Were Us, comes a second slick, fast-paced thriller about two sisters vying for the top spot on their cross-country team and the new girl who threatens to take everything they've worked for away...until she disappears. Ellie and Stella Steckler are only a year apart, but their different personalities make their relationship complicated. Stella is single-minded, driven, and intense. Cross-country running is her life and she won't let anything get in the way of being the best. Her sister Ellie is a talented runner too, but she also lets herself have fun. She has friends. She goes to parties. She has a life outside of cross-country. The sisters do have one thing in common, though: the new girl, Mila Keene. Both Stella's and Ellie's lives are upended when Mila comes to town. Mila was the top runner on her team back home and Ellie and Stella see her as a threat. But Ellie can't help but be drawn to her warm, charming personality. After her best friend moved away and her first boyfriend turned out to be a total jerk, Ellie's been looking for a friend. To her surpise, Stella too can't help but see Mila as funny, and strong--someone she can confide in, finally. As the two get closer, Stella becomes something she vowed she'd never be: distracted. With regionals approaching, the pressure is on. Each of their futures are on the line and friendship, or even something more, won't get in their way. But then, suddenly, Mila goes out on a training run and never returns. No one knows what happened, but all eyes are on the Steckler sisters.
