Plaything

This classic book in the Penny Birch series features some of bad girl Penny's dirtiest antics ever. After going a whole month without doing anything naughty, she is desperate to be even more filthy, despite her imminent departure to Brittany where she is instructed to set up a university field course. Once there, her academic responsibilities get pushed aside for more deliciously rude indulgences.
This time, however, she will encounter a French voyeur called Tom, whose penchant for dirty fun will shock even Penny and her playmates.
