Query: Strange story&#65533;

Napoli has written numerous enjoyable retellings of folk and fairy tales for the young adult audience. In this book, I felt she faltered. She tells the story of the Greek Sirens (which are pictured to be mermaids).Sirena, the main character, knows that she is cursed, being half-human. The only way to lift the curse is to convince a man to mate with them. Then, she will become immortal. Sirena decides to separate from the other Sirens and finds a castaway alone on an island. They are initially afraid of each other, but begin to fall in love. Will Sirena want to be immortal after falling in love with a human man? I found the story dragging a lot, and perhaps because the story of the Sirens isn't as well known as some of Napoli's other retellings, it seemed a bit boring to me as well. I think she has written better.
