One Pale Reflection

Brenden McCoy and his sister, Lettie, have just lost their parents and are going to live with a distant relative in Ireland. They don't know him, don't like him, and - even weirder - strange things keep happening around their new caregiver's house.

Meanwhile, in a strange other world, a mercenary has been sent by his king to hunt down and kill a fugitive, a powerful and immortal wizard. Will he be able to kill the wizard or will he die just like the other men sent before him?
