An episodic, unassuming book about the exploits of Veronique Vo and her haughty older brother Philippe, Vietnamese-French children who have recently moved from Normandy to Paris. The big city is a new and daunting place, but the Vo children are irrepressible, and they soon make all of Paris their playground. This book -- geared for middle readers -- is published by the good people at Cricket Magazine.  (FRN323, $14.95)
