A black Lab copes with the loss of a canine best friend.Bear narrates in the first person, directing remarks to the presumably deceased Barkley, who "didn't come back today." Bear's sadness is clear in both body language and text, and so is Jacob's, the dogs' human, an elementary-age White child in a puffy purple coat. Bear and Jacob walk along an obviously familiar route. When Jacob tosses "our ball" into the lake, Bear just watches as it bobs away. Bear tries to find Barkley under Barkley's favorite tree, commenting as Jacob looks up at the autumnal foliage and the sky beyond, "I hadn't thought to look for you up there"-the story's only (and very oblique) reference to a possible heavenly afterlife. Months pass, and grief still weighs down both Jacob and Bear till one day Bear carries a ball to Barkley's tree, triggering first anger in Jacob and then an outpouring: "Jacob was raining!" The two friends keep returning to Barkley's tree, where "some days Jacob rained" but eventually he laughs. This highly understated tale offers lots of openings for conversations, and an afterword about discussing grief with children should help caregivers navigate them. Yang's pastel-hued illustrations depict a suburban North American landscape, tranquil compositions allowing the text to do its work. Bear's size relative to Jacob is inconsistent, a mild distraction for children wondering whether Bear is a puppy or not.A useful book for children processing grief. (Picture book. 4-8)
