Is there a Star Wars for Dummies?

I am wondering if there is a Star Wars for Dummies with the subtitle "for people who don't care anything about Star Wars to enable them to comprehend conversations with their family members who are obsessed with it." If so I would buy it and try to read it. Star Wars means nothing to me. I have seen all of the movies but they meant nothing to me so I don't remember the stories or who any of the characters are except Darth Vader, Luke Skywalker and Princess Leia. Oh, I know who Yoda and R2D2 and C3PO are too. I have no attachment to Anakin or Chewebaka (OK, I admit, I know a few more names that I could probably match up with faces.)

Caleb loves Star Wars. He got Star Wars playing cards last year for Christmas. One deck was the good guys (Jedi?) and the other deck was the bad guys (dark side?) and he completely wore them playing all kinds of made up games with his sisters with them. They got to know so many characters because they would see them on the cards. Caleb also got light sabers for Christmas last year. I thought he was going to come out of his skin when he opened them he was so excited. What did his sisters ask for for their birthdays since then? Light sabers. They are a favorite. My brother and sister-in-law did, in fact, gave Hannah a light saber for her birthday. It was her favorite gift. Caleb gave one of his light sabers to Abigail for Christmas. Lydia still wants one. They pretend play Star Wars all the time. I just don't understand it. I don't even know if they have ever watched any of the movies (at least not that the girls would remember) besides the Star Wars the Clone Wars ones that are on the internet.

This evening they have been playing Lego Star Wars on the xbox all night. I really don't understand that game. I have tried to play but to no avail. I can't figure out how to move the characters. When I do move the characters I have no idea what they are supposed to do or where they are supposed to go. Give me a Wii remote and let me play tennis, or bowl, or play winter olympic games. I can not understand how to use the xbox controller or anything about Star Wars. The kids put together part of their Christmas money so that they could buy Lego Star Wars for the Wii. Caleb wanted me to buy it on amazon today but I didn't. I am not sure if I can handle more Star Wars. Will it be better on the Wii? I don't know. I don't know if I want to find out. Am I a bad mom to be so apathetic about something my kids are so excited about? Is there anyway I can tie Star Wars conversations into anything important and meaningful for their lives and for eternity? I would love some imput.
