Each fast moving story is around 1200–1500 words in length, with tightly controlled vocabulary and contemporary black and white illustrations throughout to help readers engage and follow the narrative. The series is growing up with the girls. In the six new titles, Siti and the sisters have a whole new set of issues to contend with—like parties, alcohol, new friends who do drugs and bad boys! Readers are bound to identify closely with the characters and their experiences.
