Ash Woods isn't supposed to perform alchemy - he'll be arrested if anyoneever finds out. But when he's caught by the condescending Ramsay Thorne, instead of handing him over to the reds, Ramsay blackmails Ash into helping with a dangerous personal mission: finding the legendary Book of Source, said to make its reader an all-powerful alchemist.

As Ash and Ramsay work together, their feelings for each other grow. But, Ash must discover his own power and find out how far other alchemists are willing to go to get it.
