I have a lot of interest in this field and want to opt this subject. I have 2 books with me: Sohail Bhatti's & Imtiaz Shahid's but they are too bad to rely upon. Could anyone mention a good book for this subject. I prefer to read 1 book and revise it for 5 times rather than reading 6 books for a single time so i would request to please mention 1 or at max 2 books ☺
