Fae War. Illusions, #3

This is the third episode of the Illusions trilogy. Yes, fairies exist, but they are not what you think. They are a sub species of Homo Sapiens with more advanced psychic abilities, mainly of hypnosis. For centuries these people, the Fae, have lived beside humanity. Sometimes they live as parasites, sometimes helping humans. Martin Harrow, Changeling, has the rare ability to create a tulpa, an object or live creature that may exist only for a few minutes.
It is the year 1930, a year of disasters and change. Now one member of the Fa proposes to take charge of human destiny. He calls himself Nemesis. Thousands of followers believe in him. Others resist. Nemesis wants Martin as a weapon. Nemesis can become invisible and inflict pain at a distance.  How can Martin and his Changeling brother Calvin resist an unseen force?
