Life got the best of me in September and I realize I have several books to post about now... so I'll do the new releases all in one to save your eyeballs!
For the Picture Book crowd: 
Mara Rockliff's CHIK CHAK SHABBAT is a wonderfully inclusive picture book about the multi-ethnic residents of an apartment building who, when a neighbor is too sick to cook, improvise a meal cobbling together their own unique traditions to celebrate the true spirit of Shabbat. The book is illustrated by the amazing Kyrsten Brooker and really has the feel of a modern classic already - Candlewick did a great job!
And lest you assume that this is a "niche" book, I have to tell you -- there is so much warmth, humor and heart to be found in these pages, it doesn't matter if you don't know Shabbat from Shinola, you'll get it. :-)

For Middle Grade readers:
WAKE UP MISSING is about a group of kids from different parts of the country and different walks of life. In fact, they have only one thing in common - they are all hospitalized in an elite institution for brain science after having experienced head trauma. When the kids realize that something VERY sinister is going on at the so-called "research" facility, they must run for their lives -- making their escape through the dangerous Florida Everglades. This is one seriously EXCITING read - and it's especially good for any kid interested in science/medicine.
"Kate Messner combines a fascinating concept with page-turning suspense . . . Reading this book is like a wild roller-coaster ride through the Florida swamps." —Margaret Peterson Haddix, author of The Missing and the Shadow Children series
