include Heather Has Two Mommies (1989) and Daddy's Roommate (1991), published by LGBT publisher Alyson Books. Both books discussed same-sex parenting and attracted criticism and controversy. The American Library Association ranked Heather Has Two Mommies as the third and second most frequently challenged book in the United States in 1993 and 1994, respectively. Recent controversies include King & King, originally written in Dutch and published in English in 2002. The book is about a prince uninterested in princesses, who eventually falls in love with another prince. In 2006, parents sued a Massachusetts school district after a teacher read the book to their son's second grade class. And Tango Makes Three (2005) by Justin Richardson and Peter Parnell has been frequently challenged, and is often on the American Library Associations's List of Challenged Books for Banned Books Week. It was ranked ninth on this list in 2017. The book tells the true story of two male penguins who adopt an egg and raise the baby once it has hatched. While it has been banned and debated many times, it has been awarded and noted by the American Library Association on their Rainbow Book List. In 2018, Little Bee Books partnered with media advocacy group GLAAD for a series of books that offered positive LGBT representation in children's literature. The partnership kicked off with Prince & Knight, written by Daniel Haack and illustrated by Stevie Lewis, which was named to the American Library Association's Rainbow Book List and was named a best book of the year by Kirkus Reviews, Amazon and the Chicago Tribune. The partnership has gone on to include books that also offer lesbian, transgender and gender non-conforming representation. Australian titles include the books in the 'Learn to Include' series: The Rainbow Cubby House, My House, Going to Fair Day and Koalas on Parade.
