Hour of the Bees, by Lindsay EagarRead about another entry on the list.
Carolina—Carol—is not looking forward to spending her summer in the middle of the remote New Mexico desert, where her family is moving her estranged Grandpa Serge into a home for individuals with dementia. At first, Carolina finds her grandfather to be a cranky old man, with emphasis on the cranky. But as the summer progresses, he draws her in with his stories of a magical tree, a long-forgotten lake, and the return of the bees. When the lines between fantasy and reality begin to blur, Carolina finds herself wondering whether her grandfather’s mind is as muddled as everyone seems to think it is.
