I have written a book jointly with Palash B. Pal. It is called `A first book of Quantum Field Theory', published by Narosa Publishing House. You can download the Table of Contents and Preface (ps file) from here. The errata are here. These corrections have been incorporated into the second edition. You can also order the book from amazon.com.
