The Silent Maiden

Mermaids live to hunt humans then drag them down into the sea for their new queen, Masika to be eaten. When Chanelle turned 16 she goes to the surfuce to hunt for the first time, only to meet a young prince and fall in love.
When she sells her beautiful voice to Masika for human legs, she must win the prince's heart within 3 days...or she will live for 300 years as sea foam.
