Girl Code: A Novel
L. D. Davis, Kate Udall

There is a strong chemistry between them that Tabitha tries very hard to ignore, but Leo doesn't make it easy. After an explosive end to their friendship during their college years, more than nine years later they are reunited, and Tabitha is again resistant to the attraction she feels to Leo.
Time, distance, and new lives have come between Leslie and Tabitha over the years, and they rarely speak or see each other, but Tabitha tries to uphold the girl code they created when they were children. Her loyalty to her old friend is admirable, but will this same loyalty destroy her chance with the man who just may be the love of her life?
