The Way Home by Nhys Glover

Those who see the ghostly figure of the WWII fighter pilot in the English farmhouse garden at Grange End are destined to die within a week of that sighting. But when Cassie Grant not only sees the Polish flying ace in the garden but talks to him in her bedroom, it's clear that something more than a prediction of death is at work here.
Hawk has been waiting for something at Grange End for nearly 70 years and from the first moment he sees the fragile beauty at the upper window he realises what it is - Cassie!

But is he there to accompany her to the other side when her time is up or is his increasingly corporeal presence meant for something else? When the enemy of the past becomes the enemy of the present, Hawk is determined to save Cassie from her untimely death, even if he has to cross the boundaries between Life and Afterlife to do it.
