The Lotterys are a large, diverse family made up of two sets of gay parents and 7 kids both biological and adopted. The parents won the lottery and decided to team up. So they now coparent, nobody works, they homeschool the kids, and they live in a big old house called the Camelottery. Sumac is the middle child of this family and has to give up her room when Grumps comes to live with them. Grumps had never met any of the family and doesn't approve of their livestyle. Yet the parents keep leaning on Sumac to try and help Grumps fit in and learn their ways. Grumps also has the beginning stages of dementia and needs to be watched. So it is a transition for all of the family when he moves in. 

There is a lot going on in this book and I think a bit of trimming down would have been helpful. I liked the idea of the blended family and winning the lottery was an easy way to make such a big, diverse family work. I didn't like the fact that Donoghue threw just about every trendy idea into the mix. The family doesn't drive, they are eco-friendly, they dumpster dive, they shop locally, they don't flush toilets, they let their yard go natural, they homeschool, they are vegetarians, they let their children educate themselves. There is nothing wrong with any of this but taken together it was a bit overwhelming! They also have "names" for everything. The back porch is called the derriere, the house is the Camelottery, and so forth. Then there was the Briar/Brian child. Born a girl, but insisting not a girl, changed name to Brian, yet the family still uses girl pronouns. I would have liked a more clear gender fluid/transgender statement about this child. It was a bit wishy-washy and really bothered me that it went back and forth. I also really didn't enjoy the audio version of this one. The narrator was a bit over the top for me. So not my favorite.
