We Love War Machines
25% off all Duel & New Vanguard titles this month
Valentine's Day is nearly upon us and we want to show just how much we love military history. The objects of this month's particular infatuation are war machines!
So we've slashed 25% off the price of all Duel & New Vanguard books, including eBooks! For Gold and Silver members, the 25% will be stacked against your existing membership discount. The offer will last until February 28th.
