Query: GRAVANO IS NO RAT

I WORK AT A BOOKSTORE AND I AM ALWAYS LOOKING FOR GOOD NON-FICTION BOOKS, PARTICULARLY MAFIA-RELATED BOOK AND I HAVE READ AND RECOMEND SUCH BOOKS AS "GOTTI" BY JERRY CAPECCI AND "GOOMBATA" BY JOHN CUMMINGS, BUT AS SOON AS THIS BOOK ARRIVED IN MY STORE I KNEW I HAD TO READ IT BECAUSE IT TOLD THE STORY FROM THE SIDE THAT NOBODY WANTED OR EXPECTED TO HEAR FROM. THE WAY THE BOOK IS WRITTEN KEPT ME TURNING THE PAGES NON-STOP. I ADMIRE SAMMY GRAVANO FOR WHAT HE DID KNOWING WHAT THE CONSECUENCES OF HIS ACTIONS WERE .PETER MAAS WAS VERY PRIVILEGED TO WORK WITH SUCH HONEST MAN AS MR. GRAVANO.
