Princess Penelope and her pig Lollipop are learning to read. Since Johnny, the intelligent and affable pig trainer from the first installment, cannot read either, the solution is obvious. Both princess and trainer will have a governess. When Miss Thistle doesn’t work out, Lollipop gets sick from eating a poisonous plant, and a miracle is needed; in steps Collie Cob, the conjuror, to save the day. Turns out, he knows more than veterinary medicine, and he teaches the whole family just what they need. Now that Penelope (called Penny by her new eccentric teacher) is no longer a spoiled brat, the story lacks some of the tension that characterized the first in the series. However, Barton’s winsome pictures bring life to the story. The final illustrations promise many adventures to come as readers see a surprised Penny with proud new-mama Lollipop. Another fine choice for chapter-book readers. (Fiction. 7-10)
