– Midwest Book Review
'The text uses complex sentence structures, rich vocabulary, and excellent dramatic pacing, with a different imaginative encounter in each chapter... Full-color illustrations in a soft-focus, mysterious style are interspersed throughout the story, with lots of full-page illustrations as well as smaller ones. Every spread has some sort of illustration to help keep readers engaged. An intriguing read-aloud for younger children and an entertaining choice for independent readers who like fantasy.'
– Kirkus Reviews
'Otto, who had expected to find a literal ball of light at the end of his journey, finally understands that each kind creature he met was a little ray of light in the dark. But this expected epiphany at the book's end didn't lessen its impact. It still manages to be rewarding and will give young readers/listeners a lot to think about during a holiday that is often so commercialized.
Since the hustle and bustle and consumerism of Christmas so often drown out the camaraderie of family and friends, no wonder it's a 'secret' light. But it's one well-worth discovering, and Otto's story is a lovely reminder.'

'A magical Christmas story to share with children of all ages. Otto and the Secret Light of Christmas is a story about the real meaning of Christmas, outside of any religious context and a tale that can be enjoyed by children and adults of every culture and background. It would make the perfect story to read aloud for a preschool or elementary school! Reading Otto and the secret light of Christmas aloud is absolutely charming; the authors use wonderful, poetic language. Hearing the story of Otto and his new friends you can almost feel the snow crunching under your shoes and hear the wind howling in the tree tops.'

'This lovely picture book is a very clever reflection on what we mean by the light of Christmas... A really beautiful, mystical way to appreciate what we can all gain from the festive season.'
– Juno Magazine
'The illustrations were beautiful and lots of effort was put into them. The artist did a great job with blending color and using light. Each picture was a great size and one on nearly every page... This would be a fun series, and Otto could go on other journeys to figure out other holiday meanings! I was eager to see what Otto would find out, and you should read it, too.'
– Kids Book Buzz
'A beautiful Christmas tale that is rich in references to Finnish folklore and culture, and the soft, intricate, glowing illustrations added so much to my appreciation of the story. I enjoyed the richness of the language. The descriptions of the forest, scenery, and characters are absolutely magical, and new vocabulary is used. I can imagine parents and children cuddled up, drinking hot chocolate and reading this book together over the Christmas holidays. The kindness and generosity that Otto encounters throughout the story are a nice reminder of how people should behave. The format of the book is pleasing too- it's a large size with a sturdy cover. Every spread has an illustration, and the text is divided into short chapters that will help young readers keep pace with the story, and will make the book a good bed time story to read over the course of several nights... VERDICT: I think this book will become a holiday favorite at my library in the years to come.'
