Fast-Paced YA Thriller With Sister Drama

Love a good book about some sibling rivalry! I'm a huge fan of Jessica Goodman's They Wish They Were Us, so I am stoked that she came out with a new book! This book is a fast-paced thriller about two sisters, Stella and Ellie Steckler, vying for the top spot on their cross-country team—until a teammate’s disappearance throws their lives off course. The sisters are only a year apart but they could not be more different. The one thing they have in common is their new friend Mila Keene. But one day Mila disappears and all eyes are on the Steckler sisters. This sounds so good!
