"I laughed so hard at times that my jaws ached!" - Dennis N. Griffin, award-winning true-crime author of The Rise and Fall of a "Casino"Mobster: The Tony Spilotro Story

"In his book UNDERWORLD, Roman Martín has hit a home run. It is amazingly well-researched and jam-packed with stories by sources whose names will be very familiar to Mob enthusiasts. While the stories and other matters addressed are accurate descriptions of serious things, such as murder and mayhem, they are told with humor and may often have you laughing hysterically. Congrats, Mr. Martín, on a job well done." - Dennis N. Griffin, author of Surviving the Mob and Rogue Town

"I couldn't let go of it! I read and laughed out loud the whole LA-to-Amsterdam flight. I feckin' love Martín's 'voice.' Kudos!" - Alex Rotaru, award-winning documentary filmmaker and playwright

"As a decades-long associate of the Chicago Outfit, I thoroughly enjoyed Roman MartÍn's book UNDERWORLD. He accurately describes 'the Life, ' and the pros and cons of becoming a mobster. But he does it in a very unique manner that will no doubt have you in stitches at times. I highly recommend it." - Frank Cullotta, co-author of CULLOTTA: The Life of a Chicago Criminal, Las Vegas Mobster, and Government Witness, and former crime partner of Tony "the Ant" Spilotro (Joe Pesci in Casino)

"If you only read one book about the Mafia in your entire life, you should read this book. Actually, you should probably read The Godfather by Mario Puzo instead. But if you only read two books about the mob, uh, well, never mind - you should then maybe read Wiseguy by Nicholas Pileggi. Okay, fuck it, if you read only three books about Cosa Nostra, then you should read UNDERWORLD!" - Marco "Babar" Falcón (self-proclaimed ex-half-assed wiseguy)

"As a former associate of the Colombo organized crime family, I thoroughly enjoyed reading UNDERWORLD by Roman Martín. If you are into true accounts of organized crime told with a sense of humor, this book is a must read." -- Orlando "Ori" Spado, the "Godfather of Hollywood" and co-author of The Accidental Gangster

"At the end of a global thermonuclear war, there will be two things left
on this planet: cockroaches and Roman Martín." - J.R., former federal public defender (Northern District of California)

"Hemingway, Faulkner, Steinbeck, Fitzgerald, Twain, Salinger, and Martín. No doubt history will find Don Roman taking his rightful place among the pantheon of America's greatest auteurs." - Roman Martín (no relation to the author)
