"I think if all big questions were asked in such an excellent mix of humour, terror and surrealism, I’d want to get to the bottom of a lot more mysteries. I loved every page." – Kate Beaton, author of Hark! A Vagrant
"I absolutely love the way it looks. The series wasn’t on my radar beforehand, but a certain print caught my eye as I was walking by the table, and I ended up leaving with both the print and all four collections of the comic that he had on hand." – MTV News
"The book’s ending offers food for thought, and is open to interpretation as the conclusion of the search described in its pages, or as the renewal of yet another cycle. Entropy is entertaining and bizarre, but also deeply contemplative. It’s a unique offering that compels multiple readings." – Foreword
"We’ve been defeated by our own desperation to explain ourselves and our universe, and the psychological clutter created by it all. If entropy is an inevitable disorder in the universe, Costain suggests that it is created by the human desire for order — and that is the creation we should be concerned with." – Comics Beat
"I’ve had the pleasure of watching this book grow, with Aaron, through the years into a sprawling meditation on spirituality and nature. I loved it." – Matt Forsythe, Adventure Time, Ojingogo
