I met author-illustrator Brendan Wenzel at last year’s Book Expo in NYC where he was signing his book, “They All Saw a Cat.” And in February 2018, he deservedly won his first Caldecott Honor Award. His new book, “Hello Hello” (Chronicle, March 2018), published this week, is absolutely EXQUISITE! The illustrations are colorful and powerful, and full of “WOW.” I loved turning the pages to see all the dynamic and vibrant animal pictures. In addition to the beautiful illustrations, Wenzel writes an important note regarding the animal ecosystem. He identifies every animal that is either vulnerable or endangered. I cannot emphasize what an engaging, awe-inspiring book this is!
