Free The Chronicles of Jonathon Postlethwaite: The Seed of Corruption by David S Denny

for years. He was ready and willing to take that nerve shattering first leap to new freedoms.
                                Within months of that maiden leap Jonathon was completely at home on the roof tops. He now saw that, out in the world of the Whisperer, the Tans and other city dwellers, including many who found refuge here, but did not have the Whisperer lore or training, were no physical match for them.
                                Jonathon's now superb  athleticism  allowed  him to travel far and wide across the city, high above its crowded streets, with same relative ease as his friends. No place was safe from them, particularly Milly who broke the rules and took risks to gain access to places which few, if no other human beings, even in this overcrowded place, had never seen.
                                The Whisperers came and went as they pleased, scaling walls like flies, dropping down from the roofs into the narrowest of recesses and chimneys to help themselves to the necessities of life wherever and whenever they wished.
                                The dwellings of affluent Tan leaders were their favourite targets. They were always rich in bounty, they supplied the needs of the Whisperers easily and always with the added pleasure that the Tans, the tyrannical rulers of the Lower City, were virtually helpless to pursue them.
    Jonathon was happy with his new, free lifestyle, but always in the back of his mind was the spectre of Silus Flax who, Jonathon knew, would haunt him until he had fulfilled his oaths against him. Jonathon would hunt him down and destroy him, but not yet. He would wait until Flax's had his beloved dreams in sight and then deprive him of them just as he had deprived Jonathon of those he loved.
                                Flax loved no-one, it was an emotion which  he could never feel. Just as many of the inhabitants had lost the ability to love and now lusted for power and pleasure without inhibition, so had Flax. But the intensity of his lust for these things  was  magnified  by  the  malignant  soul of Dubh which was using him as a tool, as a proxy of the physical self it desperately tried to achieve.
                                But Flax was not merely its a puppet. There was corrupt empathy, a resonance, between his dark soul and Its own spirit which united them. He had his own ideas; his own plans and It relished them too, gave him the motivation and helped to provide the right conditions in the city for Flax's dreams to germinate. Jonathon aimed to frustrate the lust that drove Flax towards his dream. Just when Flax had all he needed within his reach it would be snatched away.
                                The more Jonathon observed in  his  travels across the city, the more he was able to learn of Flax's activities and the general moral degeneration to which humanity had sunk in Dubh.  The  corruption  and human degradation that the newly fledged flyer saw made him more determined to see it all, and Flax, destroyed.  Dubh  was  spiritually  diseased,  a corrupt cyst waiting to burst into the healthy tissue of the surrounding dimensions and the life which existed there. The extent of Jonathon's mission was widening and becoming clearer. As long as corruption remained here, confined, isolated, it might eventually destroy itself. But Jonathon knew, from the minds of  his  Flax's  minions that these High Hats sought a 'door' from this world to others. If, and when they found it, the malignancy that multiplied here could escape to realms beyond. Jonathon would not allow that to happen.
                                At the moment he could only outline the solution. So far he had neither the knowledge nor means to carry out
