"Shaka Robinson, his twin sister Katy and his friend Darry Mbana are trapped inside the magic computer called SAM. Will the guardian of the web, the monster tarantula Chandira, let them escape alive ... will she come out of the computer with her army of monster insects and take over the world? How can they stop her? And what secret does she guard? Does she know who murdered Professor Sam Starlight, the inventor of SAM? Helped by the computer's mouse, Squeeky Lee, the children must use all their wits to get through the computers maze before they can uncover Chandira's deadly secret - and then try to defeat her by working out the riddle of her "third eye". But if he ever does get out of the computer, Shaka knows his future looks bleak. He has to undergo a crucial reading test with fearsome Mr Langman, the school inspector, known as Langman the Hangman ... SAM has been teaching Shaka to read, but he has such a weird reading problem it's unlikely that he will ever pass the test and be promoted to the next grade. Will he be doomed to stay in his grade forever? Only the fighting example of Shaka the Zulu King, the boy's ancestor, can show him the way"--Publisher's website.
