According to Wikipedia: "Stephen Frey is a best-selling author who writes novels set in the financial world. He is a managing director at a private equity firm, and lives in Florida. He previously worked in mergers and acquisitions at JP Morgan and as a vice president of corporate finance at an international bank headquartered in Manhattan.
Until the publication of The Chairman, introducing the character of Christian Gillette, Frey's books were all standalone stories. Beginning with The Chairman, Frey published four books about Gillette and his association with the private equity firm of Everest Capital. The Fourth Order, is a departure with a story line taking on the timely issue of domestic spying, although it is set in the world of high finance like his previous works."
