The most recent edition of Publisher's Weekly gives the upcoming Knuffle Bunny Free: An Unexpected Diversion a starred review saying:
"Willems's affectionate saga comes to a reassuring end, letting readers know they can release the treasured objects of childhood without losing their identities or their families' love."
Thanks to PW.
KBF has also been named on the always excellent Indiebound Next List for Children 4-8 with this fantastic quote from an indie bookseller at Brookline Booksmith in Brookline, MA:
Yay! I hope you enjoy the book when in releases in a few weeks.
"This is, no doubt, the best picture book Mo Willems has ever produced!"
And here's a nice mini-review of City Dog, Country Frog from the Fredricksburg paper.
