Tie-ins are kin to souvenirs, and in some ways are not vastly different from the dolls, toys, games, calendars, clothes, and other paraphernalia generated by successful motion pictures and television shows. Those who write them usually dismiss them with embarrassment or contempt, or brag about how much money they made for so little work. Yet, when pressed they will speak with pride about the skill and craftsmanship that went into the books and assure you that the work is deceptively easy. And if you press them yet further, many will puff out their chests and boast that tie-in writers constitute a select inner circle of artisans capable of getting an extremely demanding job done promptly, reliably, and effectively, a kind of typewriter-armed S.W.A.T. team whose motto is, "My book is better than the movie."
We don't necessarily agree with him about the motto, but we certainly take pride in the work.
