Sumac Lottery is nine years old and the self-proclaimed "good girl" of her (VERY) large, (EXTREMELY) unruly family. And what a family the Lotterys are: four parents, children both adopted and biological, and a menagerie of pets, all living and learning together in a sprawling house called Camelottery. Then one day, the news breaks that one of their grandfathers is suffering from dementia and will be coming to live with them. And not just any grandfather; the long dormant "Grumps," who fell out with his son so long ago that he hasn't been part of any of their lives.
Suddenly, everything changes. Sumac has to give up her room to make the newcomer feel at home. She tries to be nice, but prickly Grumps's clearly disapproves of how the Lotterys live: whole grains, strange vegetables, rescue pets, a multicultural household... He's worse than just tough to get along with -- Grumps has got to go! But can Sumac help him find a home where he belongs?
The plot was good how ever there were entirely too many characters to keep track of. As this is an ARC it isn't a huge concern but I also had an issue with the formatting of this book. This book is supposed to be middle grade book and if I couldn't keep track of the characters then I don't know how they would.
All in all it was a good book and it was culturally diverse. The characters all have unique names and it is a fun world that invites you in. Besides the issue I had with the onslaught of characters in the very beginning it was a good book.
