Tracy Blom is a best-selling author with over twenty published titles in bookstores, museums, zoos, airports, and major retailers across the United States. Every book she has ever created first began as a dream, written and recorded in one of many dream journals. Dreams are the common thread that wind between her stories, and for a long time, was perplexing to even her. Over time, she came to understand and cherish the gift of nightly vision and went on to create fairytales, young adult novels, and lighthearted picture books. If you look closely, you can decode the underlying messages in her work, most of which encourage readers to believe in themselves, embrace their differences as gifts, and make the world a better place.
