My novel, Riven: When Storms Collide, begins with the elf Tinachore returning to Ceridwen the cup that had been stolen from her. In the years it was lost, her anger festered. Now it will erupt. This is how the prologue ends and the trouble begins:
Tinachore looked down, away from a fury so fire-bright it frightened him.
“What can I give you to show my gratitude?” Ceridwen asked.
Tinachore swallowed. He had not dared to dream for more than freedom. “It is enough that the wrong has been righted.”A sound like the snarl of a wild cat escaped the goddess. “No. Not enough. The wrong is not yet righted. Those two must pay. You have my blessing. They will receive my revenge.”
In the novel, we quickly see the shape her anger takes. You can pick it up from the usual online locations, but it is also available as an audio book on Audible.
