The Seventh Devil

When nineteen-year-old Verity Darkwood, homeless and devastated by guilt, takes refuge in a bar to escape the unwanted attention of a stranger, she doesn't expect to meet Gareth Winter, let alone become business partners with him. They discover that they each possess the ability to interact with the world "beyond the veil" and, with the help of Horace Greeley III, editor of the fantastical online journal The Echo, Verity and Gareth spend the next two years successfully crossing over the ghosts who haunt their clients or getting rid of the demons that plague them. But when they stumble upon a series of child disappearances which are eerily similar to the circumstances surrounding the loss of Verity's younger sister, they embark on a journey that will take them across Canada in their quest to find The Seventh Devil, the dangerous and mysterious figure who may be behind it all.
