Sydney Dadzie-Granger knows that she was adopted. Her parents are Jean and Hugo Granger, both dentists, while her sister, Hermione, is a complete book-nerd. Sydney doesn't know much about her real family - just that she has the last name of Dadzie. The year that Sydney and Hermione turn eleven, they receive a strange visitor in an emerald cloak who invites the girls to become students at Hogwarts School of Witchcraft and Wizardry. Sydney discovers a new world hidden within her own, making friends, enemies, and allies. Together with her sister and her friends, Sydney unveils mysteries and that which is meant to stay hidden. Book One of the Sydney Dadzie series (set in the Philosopher's Stone).

After an adventurous first year, Sydney Dadzie-Granger is more eager than ever to study the history of the Dadzie family and what it means to be a Powerful One - even if that is a direct defiance to Albus Dumbledore, the Headmaster of Hogwarts. Continuing to grow under the tutelage of Minerva McGonagall and Pomona Sprout, Sydney begins to explore alternative ways of learning that will put her abilities to the test. But a peaceful year at Hogwarts does not seem to be a possibility: the Chamber of Secrets has been opened again, and students are being attacked. Sydney must find it within herself to claim her Heirship and face her fears, or risk losing everything. Book Two of the Sydney Dadzie series (set in the Chamber of Secrets).
