This document compares the children's book series Animorphs from the 1990s to the more recent Twilight series. [1] Animorphs targeted a narrow age range of 9-13 year olds and focused on themes of war and morality without romantic relationships, while Twilight attracted readers as young as 12 and older due to its themes of love and relationships. [2] The author argues that children's media now includes more adult themes like sexuality in a bid to attract wider audiences, which may influence young readers to seek out content meant for older viewers. [3] Harry Potter is presented as a model that balanced themes for both children and adults in an age-appropriate way.
