Edge (61 books as George G. Gilman) Adam Steele (49 books as George G. Gilman) Edge Meets Adam Steele (3 books as George G. Gilman) The Undertaker (6 books as George G. Gilman)
Interesting in that it has Edge in a more urbane setting than normal, the book starts off in San Francisco and features an art heist. A fun quick read with some decent, brutal action.
