298 THE UNPARDONABLE SIN

It didn't take them long before they reached the place that Lady Thana was mentioning. It is in the back part of the Castle, an area which she didn't try to go through.

"It is inside the labyrinth?" 

Zoe swallowed hard as she scratched her head. She has often seen this place from the Castle Towers. But she has no idea that there could be a mysterious garden inside it. 

'Yes, your Highness. The Castle is intentionally structured to guard the Garden, thereby guarding the Tree."

Lady Thana stepped forward and was about to enter the maze when she realized that Zoe was not following her.

She turned her back and saw her spotted in her place as if hesitant to come with her.

"Maybe I should go some other time. I will ask permission from my husband."

 Lady Thana's face lifted into a smile as she replied. "All right. But don't you want to just take a peek? See what it looks like?"
