What is the author's style in Impulse by Ellen Hopkins?

Ellen Hopkins tells her novel "Impulse" in the first-person perspective, narrated by each of her three main protagonists, Tony, Vanessa, and Conner. This is done because the themes and subject of the novel are vastly personal, and the best way to tell the story Hopkins tells is to let the character tell it themselves.

Ellen Hopkins divides her novel "Impulse" into 111 chapters. Each chapter is told by one of the three main protagonists and the events portrayed are chronological, though characters recall memories from time to time. This allows the story to move faster without dragging the reader down to one character.
