Andersen Press has bought two children's novels, Sorrowline and Timesmith, by debut writer Niel Bushnell, with both featuring Jack Morrow, a boy who discovers he can time travel.
Editorial director Charlie Sheppard bought UK and Commonwealth rights, excluding Canada, from Juliet Mushens at Peters, Fraser & Dunlop. Andersen Press plans to publish Sorrowline in 2013.
In the stories, hero Jack Morrow can move through time using "sorrowlines", lines that connect every grave to the day of that person's death.
Sheppard said: "I'm thrilled to be publishing these books. I haven't read anything so original in quite some time and Niel is a great addition to the growing Andersen Fiction list."
Mushens added that the books were "incredibly atmospheric and exciting".
