^Sorry Trip's current direction isn't working for you. That decision was out of my hands, though, since previous novels have already established the future path of his life.
Apparently the book uses a font that renders the numeral 1 in a way that resembles a capital I. I noticed something like that in the PDF, but it seemed to go away when I enlarged the text enough, so I thought it was a display glitch. I guess it turned out a little differently when actually printed.
S&S used the same font for the eBook and it does look like an I for the number 1.
