How is Annie described in the novel, On Mystic Lake?

Annie is described as always believing "the best of everyone" and always caring for others. Her father describes her as someone who does not "understand despair or weakness, not really. You can't get your mind wrapped around hopelessness." Annie is very much a typical romantic heroine, with the standard "heartshaped face" and a strength and resolve that enable her to unwaveringly stand up to Blake within weeks after he has left her.
