Mischief-makers Prince Lucas, his best friend Clara, and Ruskin the scarlet dragon learn to respect the hard work of others when they are sent to Flatfrost to fetch more ice from the giants who live there.

Eight-year-old Lucas, Prince of Wrenly, is eager to explore and Clara, daughter of the queen's seamstress, knows the kingdom well, so they team up to find a lost jewel and visit all of the land's main attractions as they search.

When a legendary sea monster starts making waves in the Sea of Wrenly, Prince Lucas and his friend Clara travel to the Island of Primlox seeking information that might help them calm the beast.

"Prince Lucas would rather be enjoying the outdoors with his best friend, Clara, than learning to play the lute, until a visiting bard demonstrates the power of music"--

Lucas and Clara are floating on a raft when a wave casts them into the sea, where Lucas catches a glimpse of a coral kindom and a dark-haired mermaid helps him, but when his father, King Caleb, hears of this, he scolds Lucas and tells him he has broken an age-old pact.

"As Lucas and Clara set out to investigate some mysterious happenings in Wrenly, they discover a young horse with wings that is lost and in danger"--

Clara, Tublock, and many others compete to become one of the ultimate defenders of the Kingdom of Wrenly, a member of the elite Knight Spires.

"Dire wolves are among the rarest creatures in the Kingdom of Wrenly. The only proof that these beasts exist is what they leave behind: giant paw prints and haunting howls that echo on the wind. So when Prince Lucas and Lady clara find a lost dire wolf pup, they must use all their skills to find the hidden den of wolves."--Back cover.

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 him.

The people of Wrenly have always believed that goblins are dangerous creatures who were stripped of their magical powers by wizards after the Goblin Battles; and when Prince Lucas and Clara follow a young goblin, Zark, who has come from the wizard Grom, they find themselves captured by the goblin leader Golart, who has taken over Hobsgrove--but Grom has a plan, and it requires that the children put their trust in Zark.
