Horseflies

Carole Hanson has never considered school one of her favorite things. She isn't a bad student, but she'd much rather spend time with horses than with algebra equations until she starts doing a research project on famous horses in history and literature! Carole had no idea school could be this much fun or this interesting. However, in Carole's rush to learn all she can about the past, she forgets about the most important horse of all, the one right in front of her, Starlight.
Can Lisa and Stevie help Carole regain her priorities? Or is their friend lost to the past?
