Polacco's (The Keeping Quilt) knack for spinning seemingly disparate characters and plot elements into personal yarns works to great effect in this holiday picture book, based on a "true story" told as a church homily. Jonathan resents his Baptist preacher father's reassignment from Memphis to a dilapidated church in Detroit, and he's dismayed when damage from a blizzard ruins months of planning to restore the building in time for Christmas Eve services. But the elegant-looking, bargain-priced tapestry he and his dad purchase to cover the damage miraculously brings about the reunion of an elderly Jewish couple separated decades earlier during the Holocaust. Though the tale slows in spots, Polacco's signature illustrations of swirling snow, the fine tapestry and numerous love-filled faces invite readers to linger. All ages. (Sept.)
