4.5 stars, rounding down to 4. Would have rounded up to five, more on that in a few moments. First, let me share what's great, even outstanding about this book, which was recommended to me by niece, who turns 10 next month. Our main character is Isabella ("Izzy"), an 11 y.o. in Ohio, and her voice comes across as authentic and the character as one I loved "hearing." (There were a few times I could hear the author and not the child, but it was only once or twice.) Isabella's parents are divorced and not amicably so, and the almost literal tug-of-war that she's caught in is quite well-expressed. "Blended" thus partly refers to Isabella being part of a blended family, but it also refers to Isabella herself, as her father is African-American and her mother is white, and thus Izzy must navigate racial and identity issues as well.
The book is a very quick read. A couple of the reviews I read gave away a big twist that happens in the last 30 or so pages, a turn of events that has been compared, not completely favorably, to certain other recent "big" children's or YA books. It does change the tone of the book somewhat, but not in a negative way for me. What DID spoil things for me, and why I rounded DOWN instead of up, is the RELENTLESS product/brand/store placement in the book. Cheesecake Factory, Lush cosmetics, Waffle House (OK, her mom works at one, but), Mountain Dew, Dunkin' Donuts, Skittles, Fritos, the Apple Store, Big Macs, Graeter's ice cream, Walgreen's, these and many more all figure, sometimes several times, throughout the book. Yes, our society is extremely consumerist, and that sadly includes our children, so in real life, my little nephew and niece, starting sixth and fifth grade tomorrow, are VERY much aware of all these products, brands, and stores, and VERY much driven by their preferences, and whose lives (and mine) include these points of reference, but... did the author HAVE to have her main character (and others) go on, and on, and ON, about all the stuff they love? I mean, at one point, Isabella rhapsodizes about Target, among too many other examples of how intrusive the consumerism felt in this book. If it wasn't for how much I loved the book otherwise, I would even go to a three star rating.
Ranting over. A great book, which I would recommend to both children and adults... except for all the commercials.
