This book sounds so intriguing. After reading, I really want to know where the author is going to take this book. The tension between sisters Ellie and Stella is intense and so is the rivalry. Stella has some serious anger management issues and feels the only thing going for her is her ability on the cross-country team. Ellies is the younger sister who feels some sibling tension but is really focused on her hidden relationship with Noah. The new girl Mila, is the major competition for Stella and she has to keep her jealousy and frustration secret as not to worry the school and scouts about her obsessive need for winning. I absolutely love the cover and cannot wait to get into the mystery of the killer who is taking out young runners. I cannot wait to read the rest of this book!
