Doctor Who and the Genesis of the Daleks — Terrance Dicks

Doctor Who is given the chance of his lifetime, the incredible chance to eliminate his most deadly enemy, the Daleks. Sent to Skaro, the home of their creation, at a point in time just before their existence, Doctor Who's sole mission is to prevent the Dalek's birth--or at the very least, alter their genetic development. -- But the Time Lord and Doctor Who had not anticipated the single-minded obsession of the brilliant scientist Davros--a man determined to give his invention, the Daleks, destructive powers and a ruthless intelligence, a man determined to destroy. And least of all did they expect the baby Daleks to turn on their inventor...on the entire city...and prematurely on Doctor Who.
