This is from an advance review copy for which I thank the publisher.
This was designed from the outset to be a print book (there's a page toward the beginning which has a space for the owner's name to be written in!) so it lacks the same force when viewed as an ebook which is the only format I had access to. I wouldn't recommend trying to read this to a kid on a smart phone, but on a tablet computer it's a decent size, unless the pad is one of those really small pads.
Instead of being presented as a double-page view, it featured only single pages which made it hard to appreciate the layout as it was intended to be seen. I don't know why ebook versions do this - some which ought to be seen as single page images are instead presented as double, and vice-versa. It makes for an irritating read in some regards, and not something suitable for a small screen, but once I got past that, I appreciated this book for young children which talks of fear and bravery and friendship.
Percy Penguin is a tear-away, whereas Posy Penguin is timid and reserved. This might be seen as a bit genderist, but it does comport with how many boys and girls tend to be, although it by no means is true in every case. There's a moral to this tale however, because Percy's passion for daredevil activities is what gets him into trouble when he goes off to explore a passing iceberg. Posy seems to be the only one who thinks there might be something wrong, and like a guardian angel, she steps up where others fear to waddle, heading over to the iceberg to see why Percy didn't come home.
She learns that she can do anything Percy can - and do it better since she doesn't get herself into trouble, and she learns some self-sufficiency and garners the strength to overcome her fear of the dark to boot! It would have been nice to have had the point raised about running-off without telling your parent/guardian where you're going (parents here seem to be alarmingly laissez-faire!), but that aside, I enjoyed this book carrying a lesson in a fun and colorful story, and I commend it as a worthy read.
