A SONG WORTH STAYING FOR Mavis is a world-famous singer with millions of fans, a successful band, and a voice everyone knows. When her tour brings her to modern-day Berk, she expects nothing more than another concert. But after performing her original song, “Siren,” she catches the attention of Hiccup Haddock, Berk’s Chief. Hiccup isn’t impressed by her fame. He likes Mavis for who she really is—and for the first time, Mavis finds someone who sees the girl behind the superstar. What starts as one unforgettable performance turns into a romance neither of them expected. But Mavis’s tour has an end date. And soon, she has to decide if she’s ready to leave Berk behind… or finally find somewhere worth staying.
