I absolutely loved it! 

This story was wonderfully-dumb. Full of charm and humor. I enjoyed the Ogre Sister and villains that weren't largely incompetent. Punycorn is sweet and kind, and his friends don't spend their time downing or calling each other names. 

It's obvious the Unicorn Heroes don't appreciate or acknowledge Punycorn as a hero material, but it's balanced. They don't hate him or anything. Ending spoiler:

Even Bloodgutter's character was a surprising twist. A pacifist sword that got to keep to its morals. I just find it refreshing the characters accept each other.

The artwork is seriously cute, and you can tell Watson put a lot of effort into including visual gags a well. 

The least likely can do great things!

I can't wait to read the next book!
