This book is more winter themed than Christmas (although there is a sequel called Christmas with Trolls). So, this book really could be read year round. Jan Brett can be a little hit or miss for me, but I really enjoyed this one. Clever little Treva outwits some dim trolls who are intent upon taking her dog. As with some of her other stories there is a side story woven into the main narrative. I really love it when she does this! In this one we get to see the little troll busy in their den underneath the ground. And as the trolls vacate their cave to terrorize Treva and her dog; an adorable little hedgehog finds his way in and makes himself right at home. Very cute!
