Hi! I'm Lauren and lately I've discovered something strange about my cat Saturn. Something very strange indeed . . . And this time it wasn't just me, but also my best friend Tilly who magically travelled back in time with him. Imagine our surprise to find ourselves in Ancient Rome, where no one spoke our language - and they wanted to sell us as slaves! But that wasn't the scariest bit. Because when the tremors started, and the smoke appeared, we knew our adventure was about to explode . . .
