In questions such as these, I think that the individual has to end up determining what moments they see as significant. Naturally, there are some basic elements that would be seen as universal, but the idea of constructing "ten" important events is one where nearly anything can be seen as essential. The development of characters, the introduction of side characters, as well as the growth of emotional dynamics are all aspects which can become seen as "important" events. For example, the rape of Melinda has to be seen as an important event. It sets the entire work in motion. Yet, from this many other elements can be developed. Some might or might not see Melinda's befriending of Mr. Freeman as an important element. The shunning of Melinda could be seen by different individuals as an important event. The future of "it" might be seen as another important event. Perhaps, this could be seen as another important event. I think that Melinda's embrace of art and artistic expression is another instant where an important event is evident because it provides an outlet for her ability to "speak," the very basis of the novel. I think that starting from one point and then constructing different elements that you think are important can help you find the ten events that are being sought.
