Half A Rainbow is an international haiku anthology dedicated to Rachel Sutcliffe (1977-2019), and Haiku Nook Google+. Rachel was a highly respected haiku poet from the U.K. who is published widely. She was also an active and inspiring member of our Haiku Nook G+ community. Rachel passed away from an autoimmune disease called lupus. In honor of Rachel and the Haiku Nook G+ community, 21 poets from Canada, the U.K., Germany, Persia, Sri Lanka, South Africa, Romania, Indonesia, the Philippines, and the U.S. have come together to create this anthology. Our anthology features haiku, tanka, and haibun. Proceeds will be donated to Leeds Clinical Immunology Research Fund, Leeds Cares at St. James' University Hospital.
