Dream Master: Gladiator [EPUB ebook] 

Cy has the ability to control his own dreams and knows his own, personal Dream Master. But sometimes Cy’s own imagination is so strong that he can run his own dream. Or so he thinks. For there’s plenty of mishap and adventure ahead when Cy and the Dream Master travel back to Pompeii — on the eve of the eruption of Vesuvius. Not only does the Dream Master have to face a lion in the gladiatorial ring, but Cy must rescue him — and drive a chariot to escape from the volanic lava and dust . . . The third in a fantastic fantasy series.
