I'd give 9 out of 10 if I could, but alas, we don't have that level of detail, so 4 out of 5 it is.

Jenna Moran's style is a natural fit for a children's book, and so Invasion works very, very well. Even so, the expected mind-bending perspectives that Jenna's fans so dearly love remain present, so I certainly enjoyed it. In particular, the art style helped the story immensely, the one building off of the other, to the point where I had to stop and appreciate the art to really grasp the full intent of the story, which represents an additional layer of mind candy.

Said differently, page one let me think it was a child's book. Page 2 made me quirk an eyebrow. Page 3 made me do a double take and flip back to page 2 to check the shift in art style.

So why four out of five? Format. Invasion is not a book that you'll want a PDF of. It just isn't. It's a book that you'll want on your shelf or sitting on your table so that your friends can pick it up and page through it and do the same double take you did when you first read it. For $4, it's certainly worth your money, but frankly, I think it would be better to pick it up from Amazon.com so you can amaze your friends and frighten your enemies with it.

This is one of the best children's books I've ever seen. I'd also probably need to think twice before reading it to any child. :)

The adorable art and characters you can see in the preview belies a dark story of the intrusion of an unique and chilling threat. It is the unusual, entertaining, and surprising sort of tale one can expect from Dr. Moran, and at this price it is worth every penny. :)

I had originally read, and enjoyed, this story as text-only short fiction on the author's blog. It was quite good even then, but Elizabeth Sherry's illustrations really make it stand out now.

A very interesting, very meta twist on children's picture books.
