I received a digital copy of this from NetGalley. 
 I saw this on several 'good reads for the summer' type lists, and I also noted several positive editorial reviews. This is my first title by Moriarty, and I wasn't disappointed. I read the bulk of it while traveling from CA to NC, and I never wanted to stop reading it and switch to something else, which has happened on other trips, and is a pain unless I have another title ready. 
 A gregarious, colorful couple (Vid and Tiffany and their daughter Dakota) hosts a spontaneous BBQ, where they've invited their next-door-neighbors (Erika and Oliver), along with friends of the neighbors, Clementine and Sam (plus their kids Ruby and Holly). Erika and Clementine have known each other since childhood, though their friendship is not as usual or as close as one might think after decades. 
 Early on in the book, it's clear that *something* happened at that BBQ, but we don't know what. And you won't find out exactly what occurred until a bit after the book's halfway point. The chapters, usually brief, vary in time (the day of the BBQ or the present, for example) as well as point of view. 
 As a result, you'll either get tired of waiting for the big reveal, you'll become irritated with learning so much about the characters, or both. If that's the case, this isn't the book for you. Otherwise, you'll be treated to a slow unfolding of the storyline while you happily devour the solid character development Moriarty has given to this small group of people. 
 I liked the writing, I liked how the characters were fleshed out, and I strongly liked how all of my questions were answered and resolved by the end. The exploration of marriage, friendship, parenting, and even the dynamic between neighbors is looked at in a way that kept me happily reading until the end. 
 I'll recommend that our library purchase this title!
