Lexi, a precocious squirrel, and PeeWee, an abandoned guinea pig, band together to help a hungry and friendless man in this latest Park Pals Adventure. Growing up in Central Park, Lexi has learned a lot from observation and even more from his enormous family. Wisdom like “Go dig for nuts, don’t dig for trouble” prevents Lexi from helping the man initially, but PeeWee’s trust and compassion convince Lexi and together they help the homeless man find food and eventually reunite with his family. Humorous anecdotes about the lives of squirrels and their views on humans add to this charming tale. Pen-and-ink drawings scattered through this small book depict Lexi training for the upcoming Squirrel Circus and show PeeWee’s amazing ability to read. Although occasionally didactic, no one who reads this will ever look at these furry little creatures in the same way. (Fiction. 7-10)
