The Ball Kids And The Tent With The Blue Cross [EPUB ebook] 

The long day — After a half decent ride on the train and then whisking her way through the steamy streets and back alleys and now finally into the last laneway.
The strange day — Sal looked to where the can had landed and noticed it was moving, funny that’ she thought due to there was no wind, breeze, not a whiff of anything.
The responsibility — Her little brother Levi, thought Sal, he could look after himself, coming to think of it he could even look after me. At last the day’s final and fun offerings. But what will be next for Sal will take more than throwing a tennis ball correctly back to a famous player.
It would take more of what Sal ever thought she had. But will it be enough?
