"[The] action-packed adventure sequences move at an exciting clip...Part fantasy...and part manga, this volume has much appeal to readers." - Booklist

"Gr 4 Up. Hurrying to pick up her brother, Emily and her parents have a tragic accident, and her father dies. After this dark beginning, the story skips forward two years to when the remaining family members are forced to move to an ancestral house in a small town. Rumored to be haunted, it is unkempt and forbidding. The first night there, Emily's mother goes down to the basement to investigate a noise and doesn't return. The kids search for her and discover a doorway into another world, where their mother has been swallowed by a monster and is being taken away. An amulet that Emily found in the house tells her that together they can save her, but her brother isn't so sure that this voice can be trusted. Still, what other choice do they have in this strange place? Gorgeous illustrations with great color bring light to this gloomy tale. Filled with excitement, monsters, robots, and mysteries, this fantasy adventure will appeal to many readers, but it does have some truly nightmarish elements." School Library journal
