A Wind in the Door has very scientific elements that make it both entertaining and educational. Many elements of the book incorperate linguistics, unlike the previous, A Wrinkle in Time. It seems that both books have very similar plotlines, and only the science behind the stories change. Both are stories of a battle betweeen good and evil, with tests of strength and morality for all characters. A Wind in the Door seems to be primarily focused on Meg, rather than on both her and Charles Wallace. Once again, Meg is forced into a situation in which she must save her brother. The storyline is very predictable, as it is almost the exact same as the previous book. There is a reoccuring theme of teachers helping the children to grow, the prescence of mythical creatures, a challenge the children must meet, and Charles wallace being in dire need of Meg's help. As the plotline is somewhat contradictiary to that in A Wrinkle in Time, the events that take place are a little confusing. Is there a darkness that is clouding Earth and bringing war and hate, or is it a rip in the galaxy? Are they related? It is all very unclear. The charateristics of the family are starting to wear, as the fact that they are scientists seems to be the only faccet of their lives. I guess that is why this is a childrens book, since they seem to be more beleiving and less critical.
