Hi. I'm just starting to self-study QFT and need all the help I can get. I already have "QFT for the Gifted Amateur" and the books by Zee and Schwartz . I am looking for another book that takes things step by step from the very basics. Was looking at the book "Student friendly QFT" by Klauber. I normally like books form lecturers/professors associated with recognizable universities so I know the info can be trusted but I don't know anything about this author. Does anyone have opinions on this book or any other book that might be suitable for me ?
