Pet By Catherine Chidgey Europa Editions: August 8, 2023 $18.00, 332 pages Pet is a psychological mystery (but not quite a thriller) involving a 12-year-old girl, Justine, who is enamored of her charismatic new teacher, Mrs. Price. Set in New Zealand in 1984, it offers a portrait of growing up in a slower and simpler time, yet one that is no less complicated when it comes to the desire to be understood and liked by peers and certain adults.
