The Chameleon Shop Book 2 (en Inglés) - Teresa Schulz

After an exciting adventure in the Five Realms, Kaylee Browne has just returned home to Feilding, through the magical Chameleon Shop, which to her surprise, has now become a chocolate shop.
Unless she returns to the Five Realms within seven days, her father will be put to death. Kaylee also fears for all her new friends in the Realms such as Jett the giant Messenger Cat and Gerard the gentle giant.
Although she dearly missed her mother, her return is bitter-sweet, having almost completed her Quest in the Five Realms, only to be thwarted at the last minute by Wilfrey. Knowing she must go back home, Kaylee has mixed emotions. Somehow she would rather face the Dragon in the Five Realms again, instead of the familiar one who was waiting for her at home.
