I just came across an article that briefly mentions this book, recommended for readers in grades 5 to 9. Published earlier this year, “The Black Canary” by Jane Louise Curry is about a mixed boy who finds himself transported back in time to the Elizabethan era:

Growing up in a close-knit, biracial American family with parents and grandparents professionally and personally engrossed in musical pursuits, 13-year-old James feels overprotected and pushed in the direction of their interests. He secretly resents the way his parents’ careers absorb their time, and he resists developing his own musical talent. While staying in a London flat, James discovers a mysterious portal, steps through, and lands in Elizabethan times. Forced to fend for himself, he begins to explore his identity apart from his family’s expectations, finding within himself an unexpected passion for singing. This is one of the few time-travel fantasies for children with a biracial character, let alone protagonist, and it includes James’ acute observations of Elizabethan Londoners’ reactions to him. Race, though, is only one of James’ concerns as he struggles to survive where even the simple question “Where are you from?” leaves him scrambling to avoid pitfalls. James is a sympathetic character in both worlds, and readers will gladly follow him for the pleasure of his company as well as the need to know what will happen next. A genuinely good story that conveys a sense of darkness and mystery in the textured backdrop of a storied time and place.
