The lives of the disparate and dynamic nine characters introduced in "One Rainy Day in May" begin to intersect in inexplicable ways, finding harmonies and echoes in each other. What once seemed remote and disconnected draws closer -- slowly, steadily -- toward something inevitable. At the center of it all is Xanther, a twelve-year-old girl, for whom the world around her seems to be opening, exposing doors and windows, visions and sounds, questions and ideas previously unknown. With each passing day, she begins to glimpse something she does not understand but unequivocally craves -- the only thing that will bring her relief and keep her new friend alive.
