Rise of the Isle of the lost. Melissa De La Cruz. 2018.

Deep beneath the waves, King Triton’s powerful trident has passed through the magical barrier that surrounds the Isle of the Lost - keeping villains in and magic out. Uma, daughter of Ursula, is determined to get her wicked hands on the trident, so she readies for the high seas alongside the toughest rogues on the Isle.

When reformed villains, Mal, Evie, Carlos and Jay hear that King Triton’s weapon has been washed away, they realise they’ll have to find it before anyone from the Isle does....
