Abby, Bess, and Cristy are best friends-period, end of story. Until Bess said, Zack's cute, and the two words sent the three friends into a tailspin. Zack, you see, was Abby's long, long, longtime crush. Gasp! Poor Abby has never even worried about the possibility of someone else liking Zack. Even if she had, she never would've suspected that the someone would be Bess! That leaves us with three puzzling questions about the three best friends: 1) Why didn't Bess think Zack was off-limits? 2) What will Abby do about it? And 3) Whose side is Cristy on anyway? For these three best friends, those three questions are just the beginning!
