One each on their shoulder, back, wrist, bicep, and ankle, Bruce, Finney, Robin, and Vance all have five different soul-marks. Each boy is marked with a baseball on his shoulder, a pinball machine on his back, a rocket ship on his wrist, a bandanna on his ankle, and a book on his bicep. Within a month after turning 16, the boys learn that they are all soulmates. So, how does shy, innocent Delilah manage to attract the attention of these 4 boys and who does the book soul-mark belong to?
