The Dream Portal, Volume 16

"There is only one place throughout the entire Kingdom of Wrenly that no one dares explore: the Dream Portal. Hidden beyond the swamps of Bogburb, this strange and ancient circle of stones was built by wizards before time began. Stories of great danger surround the mysterious monument. But when their dragon friend, Ruskin, falls under the Dream Portal's spell, Lucas and Clara will risk the legendary peril to save their dragon friend."--Publisher's description.
