And that Mum's new boyfriend, Galactic Gavin, has eyes that twinkle like Sirius, the brightest star in the night sky. And that sometimes the perfect place for her sister, Terrible Topaz, would be a black hole. But Mabel doesn't know how to fill the space in her heart that Dad left when he walked out. And so she sets out on a mission of discovery...A heart-warming and laugh-out-loud story about learning that love is never lost and change doesn't have to be scary.
