I'm not necessarily anti-book trailer. Dragon Soul Press, who published my horror-thriller mysteries Phantom Audition and The Irresistible Summons, put these two together.

I should add that these versions are no longer available, as rights have reverted to me. But both Phantom Audition and The Irresistible Summons have since been rereleased with new covers, here and here, if you're interested. :)
