The Therapy Room trilogy in one volume.
The Therapy Room is an unusual business. The owner, Oliver Weir, is a regression therapist who helps people with problems that more orthodox methods cannot cure.
The English Civil War, the Great Plague and World War II are visited in order to help people cure their present day problems by deciphering the enigmas of their pasts; but can Oliver resolve his own issues in order to save himself from his own past?
