Befriended by Nina, who suspects Masterly's motives, Darryl slowly uncovers a sinister plan and finds himself the star in his own real-life computer game. But will he and Nina be able to stop Masterly and escape before it is too late?Brainboy and the Deathmaster is a fast-paced, high-tech mystery-adventure by National Book Award finalist Tor Seidler, author of the modern-day classic Mean Margaret.
