Mongoose Publishing has taken the Spinward Marches and brought it up to date for the 21stC. Martin Dougherty's eminently readable text is easy to understand yet imparts information about The Marches in a useful fashion. There are hints, nudges and nods to older Traveller materials throughout the book and ttis makes the book usabel with earlier versions of the game. I recomment this book to those new to Traveller and to old hands. The Marches are back!
