A palette with daubs of time travel, artists, magic, evil, and possession paints an intriguing mystery. When his mom suddenly starts acting strange, going into trances, and removing all television sets from the house, 11-year-old Connor figures out that an art book about the painter Fitzgerald Cotton is the key. When he finds a loose sketch of his mom, he is transported back to 1926 to the Cotton family house, the same place where his mom had been summoned by Fitzgerald to serve as his muse. Piece by piece, Connor discovers that the paint powders from 1479 belonging to an evil genius/artist, Lorenzo da Padova, possess Fitz. Connor’s mom is a distant relative to Lorenzo’s muse and looks like her, and the more Fitz tries to paint her, the stronger the hold on both of them. Connor succeeds in breaking the spell, freeing his mom, and returning home—wiser and more appreciative of earlier times and family bonds. Like the jigsaw puzzles the Cotton family put together, pieces fall into place fairly easily though readers will share Connor’s confusion and will be piqued by his suppositions of how kids from then (1926) would be old people in his time. Fans of Reiss’s Time Windows (1991) will step right into this “Time Travel Mystery.” (Fiction. 10-14)
