In the last year or so, Kirkus reviews changed their review policy to try and better identify diverse books for readers. In an article by Vicky Smith from last may, (https://www.kirkusreviews.com/features/unmaking-white-default/) she writes "But as the conversation surrounding diversity in children’s literature has heated up, I’ve felt more and more that naming race and identity is one of the duties of a reviewer." I understand her point. Covers and plot descriptions of novels are not necessarily indicators of race or sexuality, and for those who are seeking books with diverse characters, this makes discovery a challenge. On the other hand, I also think that there has to be a measure of how relevant or important those details are to the story, and whether or not it's necessary to call attention to it.
