Patricia Reilly Giff is known for her historical fiction, and her most recent book is an excellent new addition to the genre. Gingersnap is set in New York during World War II (Wendy Lamb Books, $15.99). Jayna lives with her older brother Rob. After their parents’ accident, Rob took custody of his sister as soon as he turned 18. When he’s called to duty, the only person left to care for Jayna is the landlady. Whether inspired by ghosts, voices, or her own intuition — the reader is left to decide — Jayna leaves the landlady’s house, sets off, armed with her turtle, and follows the clues left in an old suitcase in Rob’s room. A recipe book written in French and an old photograph lead her to Gingersnap, a bakery in Brooklyn, and a woman that Jayna desperately hopes is her grandmother. Conveying the realities and hardships of life on the home front, Gingersnap, demonstrates that love and good food are two key ingredients in creating a family.
