Part of Your World (Twisted Tale Series #5)

What if Ariel had never defeated Ursula?

It's been five years since the infamous sea witch defeated the little mermaid... and took King Triton's life in the process. Ariel is now the voiceless queen of Atlantica, while Ursula runs Prince Eric's kingdom on land. But when Ariel discovers that her father might still be alive, she finds herself returning to a world--and a prince--she never imagined she would see again.
