It is a compilation of titles reviewed in VOYA magazine that received a perfect 5P and 5Q rating in the 21st century. VOYA"s young adult book reviews have helped build young adult library collections since 1978. Many young adult librarians rely on VOYA"s reviews as their main resource for book selection.

Printz, John Newbery, Coretta Scott King, Best Books for Young Adults, Quick Picks for Young Adults, Teens" Top Ten, Popular Paperbacks for Young Adults, Guardian Award, Carnegie Medal, Best Fiction for Young Adults, Mythopoeic Fantasy Award, USA Today Bestseller, Nonfiction Award, Morris Award, and the Edgar Award.
