Geboren in Lissabon, Portugal. When he was six, his family moved first to London and then Dundee, Scotland. He received a degree in mathematics at Dundee University, and in 1983 moved to London without a job and bluffed his way into writing computer games for a local firm. Some time later, a friend whose company produced tabletop wargames asked Pinto to design a world. This led to the self-publication of his first book, Kryomek. Further work in gaming, that allowed him to continue writing, finally led to the sale of the three-volume epic The Stone Dance of the Chameleon, the first volume of which, The Chosen, was published in 1999.
