I HAVE SO MUCH LOVE FOR THIS BOOK! From the little messages about life and friendship and family that were weaved into the story to the kids and the PARENTS (Felix is Dad of the year oh my god) and the Plot and - I just loved everything about it. It was funny and entertaining and adventurous and just so much fun! It had an awesome Plot Twist. It was very imaginative with polar bears and unicorns and tiny dinosaurs. It was basically everything I want from a good Middle Grade Fantasy. I would recommend it to everyone who loves friendship and a good adventure! 5 Stars! Obviously. Can't wait to read the Second book!
