Thomas is a beautiful baby and his sister, Mollie, makes a mistake one day and tells him that. People are never supposed to tell the children how wonderful they are, because the Kinde Folk (a group of evil fairies) will carry off the child and replace it with a horribly ugly and ill-behaved one of their offspring.

This is exactly what happens to baby Thomas and the family is left with a biting, screaming changeling that Mollie calls “Guest”. This being throws the family into an upheaval as it wears Mollie’s mother down and drives her father away. Granny Hedgepath advises to keep the child safe and happy, so that the Kinde Folke will possibly (although highly unlikely) return Thomas. Mollie and her mother are near the breaking point, when Mollie decides to travel with Guest to the Darklands and hopes for a trade to bring her brother home.

Her journey is dangerous and may end in death. But, Mollie is determined to reclaim her brother, return Guest and make things right again for her family. Along the way, she meets some that may help and others that will try to kill her and keep her brother. The ending is a twisting and turning series of events that will surprise the reader almost as much as Mollie herself.

This is not a typical ghost story by Mary Downing Hahn. It is based on Irish myths and appears to be set in a village in the middle ages. Therefore, there is magic, both evil and good. An afterward explains the background of the story and might lead to further exploration. The fantasy elements work well and the story moves along. The scary parts are just scary enough and the reader’s imagination will paint some wonderfully dark pictures as the story progresses.

Recommended for libraries looking for more scary stories that have a bit of fairy dust (not the good kind!). Students will become invested in the journey and eventual, somewhat surprising, ending.
