A handsome companion to Underwater Counting: Even Numbers (Charlesbridge, 2001). Pallotta still counts by twos, but slips into the realm of odd numbers, which may prove a slight challenge to readers conditioned to even numbers. However, he does slide into the "evens" for the numbers 50 and 0 at the end of this eye-catching book. Bersani's bright, realistic colored-pencil illustrations will lure readers into perusing the factoid-loaded, simple, conversational text. From "1 Striped Bass" to "23 Horseshoe Crabs" to "50 Blue Sharks," this book offers a colorful, engaging, and intriguing slant on the technique of counting.–Patricia Manning, formerly at Eastchester Public Library, NY
