Mr.Taran, For practicing & learning "Intermediate Urdu", you can consult and read from Gopi Chand Narang's "Literary Urdu Prose", "Khushboo" by Nastaran Ahsan Fatihi. "Sir Sayed aur Urdu Sahafat" by Mohammad Jahangir Warsi.
Same time BBC Urdu.com is also a good source of Urdu Literature. Feel free to ask me about your specific reading literature. Keep up this good work.
