[1] Three young adults named Arthur, Lucy and Elizabeth were traveling to meet Rupert Steiner, who had received a note from Gadzooks.

David and Zanna get home one night and discover their neighbor, Henry Bacon, is in the hospital due to a stroke.

After Henry dies, Gwilanna, attends the funeral and gives a warning to David that she will do anything to get her hands on the obsidian and the Dark Fire.

Zanna goes into town with Alexa and Gretel to open her shop, but on the way the group are attacked by the semi-Darkling flock and are rescued by Tam, who destroys them with the spirit Kailar.

Tam talks to David about Rupert Steiner, who has come to him with a story about translations of the dragontongue found on the Glacier expedition.

David then distracts the Darkling with the dark fire he already has, captures it and sends it back to the IX with a warning to leave the Pennykettle dragons alone.

However, while David explains what will happen, Gollygosh is momentarily corrupted by the dark fire, and releases it early.

Lucy and Tam arrive at their guesthouse, which is run by Hannah and Clive, and has one other guest, Mrs Gee.

They climb Glissington Tor, the dragon's burial site, that evening, and that night Lucy has a nightmare about a cat, which she encountered earlier in the day, bringing her a semi-darkling.

When Gwillan suddenly wakes up, Melanie Cartwright comes to visit with her mother, Rachel, and dragon, Glade, who can sense moods.

Gretel puts the humans to sleep so they don't get in the way, and Glade goes upstairs to try and check on Liz and the baby.

At Wayward Crescent, Zanna is puzzled by e-mails Lucy is receiving, which David tells her are from other daughters of Guinevere.

Tam and Lucy travel through the tunnels to wake Gawaine, but as the dragon stirs, Hannah betrays them.

Tam is trapped underground, and Lucy captured by Mrs Gee, but Bella helps her escape.

In the chaos of the dragon's awakening, Mrs Gee, Hannah and Clive are all killed and the hotel collapses.

One destroys her wing and poisons her blood, although it is near-fatally injured in the attempt, and falls to the ground near Lucy, who has been joined by Bella.

Zane contacts Agatha Bacon but instead Gwilanna arrives at Wayward Crescent, and Zanna leaves for Scuffenbury after .

She uses a spell to trap Arthur in an armoir and, with the use of Gawain's iscoscele, draws the dark fire out of Liz.

The dark fire turns Gawain's isoscele black, then proceeds to kill Gwilanna before traveling to Scuffenbury.
