Is there a book entitled "Romero"?

One of my igned summer reading books is "Romero". The teacher wrote down the author of each of our books except for this one. Some of my friends think that it may be the autobiography of Oscar Romero, but I can not track this book down (and find it hard to believe that he did write an autobiography, since he was killed only a few years after he began his work). So is there even a book entitled "Romero"? Where can I find it? And there is no possible way of asking my teacher about the book because she is new and has never been to any of the school's meetings.
