Bedtime stories are an important part of a child's day, but you can also expand your kid's horizons by creating your own book club. Take your daughter to the library or a bookstore, and let her choose a book that the two of you can read together. Set aside time every day to read a chapter. You can read aloud to younger daughters, making sure to use different voices for all the characters, of course. With older girls, you can opt to each read the book separately and have a special book club meeting -- complete with snacks -- to discuss what you thought of the material.
Many popular children's books have also been made into great movies, so you can also expand your book club to be a book-and-movie club. After you read the book, go see or rent the movie and discuss how the two are different.
