What is the author's style in Criss Cross by Lynne Rae Perkins?

Author Perkins has attempted to place herself into the hearts and minds of young teenagers, struggling, as they have for centuries, with the questions of their identities, their futures, and their values. She functions as a narrator with complete omniscience with at least two characters - Debbie and Hector - perhaps the two who exhibit the most maturity for their ages. Debbie, while focusing upon an upcoming summer, wants something good to happen, and that something good appears to be related to romance.
