A companion volume to Hello, Sun! A Yoga Sun Salutation to Start Your Day, this picture book by children's yoga instructor and mindfulness teacher Hinder features a blue-haired child with apricot-colored skin, wearing a spaceship-printed pajama top and fuchsia pants, as they participate in an extended series of yoga poses, or a "flow," through space landscapes before settling into bed. Extra touches of whimsy define the scenes with deep violet and blue starry-printed digital backgrounds; depictions of space travel; smiling anthropomorphic bats and insects; and friendly, pillow-shaped green aliens. Some lines are less effective than others ("Lunar salute/ the white ball in the sky"), but this offers a simple, comprehensive walkthrough of a moon salutation yoga flow for budding yogis. Back matter features a spread illustrating the full mandala flow with more in-depth instructions. Ages 4--8. (Oct.)
