BOOKLIST (STARRED REVIEW)
With never a hint of hyperbole, the authors communicate such a contagious sense of wonder that few readers will be able to resist following the final pages' simple directions for constructing a handheld snowflake observation stage and rushing outside at the first sign of snow in hopes of taking a closer look at one of nature's most beautiful and ubiquitous phenomena.

BULLETIN OF THE CENTER FOR CHILDREN'S BOOKS (STARRED REVIEW)
Nature photographer Cassino's galley of snow crystals is the sort of riveting exhibition that will have eyes locked to the pages, mesmerized by the intricate forms themselves and the 'How did he do that?' wonder at Cassino's technique of capturing images of these ephemeral delicacies.

CHICAGO TRIBUNE
Thought you knew it all about snowflakes? Settle down in a comfy chair, and prepare to revise your inner database....By the end, you'll be hoping there's a day when you can follow the careful directions for catching and viewing snow crystals.

KIRKUS REVIEWS
The clear and direct narrative takes readers into the clouds to explain snow-crystal formation...and then zooms in on the actual crystals. Sure to get young scientists outside in the cold, particularly as it helpfully includes crystal-catching instructions.

Libraries in areas where snow falls will definitely want to add this title to their collections, but it would enhance lessons on weather anywhere.
