Ruskin, Cinder, Groth, and Roke travel to the Shattered Shore to honor of Villinelle, and while there, the four dragons make discoveries that will help in the upcoming battle.

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.

"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"--

Prince Lucas, his friend Clara, and Ruskin the dragon travel with a team of knights to the forest of Trellis, where they discover that an evil sorcerer's shadow has cursed the land and only someone pure of heart and full of hope can save them.

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.

Ruskin the dragon and his friend Cinder are sent to Shadow Hills, the most mysterious place in all of Wrenly, under false pretenses by sinister forces.

"Cinder has left to find the truth about Villinelle, while the others are on the hunt for Valos, the evil wizard who is out to destroy all of dragonkind with beasts born from the fiery depths of Crestwood"--

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.

"A mysterious spell has hypnotized the fairies on the island of Primlox and it's up to Prince Lucas and Clara to save them"--

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.
