I have recently read a book called The End by the awesome Lemony Snicket. In this book there are three siblings who each have different traits, hobbies and interests. Violet, the oldest, is an amazing inventor as well as a very resourceful person. Klaus, the middle child, is a reader and a researcher. Sunny, the youngest, is a biter and a chef.
I can relate to Klaus mainly, but I can always picture Sunny the clearest. In this series Sunny grows out of babyhood in a very realistic and truthful manner. The author describes her journey wonderfully, slipping in small things that seem unimportant, but in The End they mean that she is no longer an infant, but a much larger person (metaphorically speaking.)
Though this book tends to be eccentric at times, I highly recommend it to anyone who loves reading books with clever plot twists, highly descriptive language and never ending adventure.
