Too easy. Too neat. What's really going on? Sunny is very motivated to find out. After all, it doesn't get any more personal for Sunny than Richie.
I see on Goodreads that some readers have bitched and moaned because Sunny is "too liberal" and shares her dislike for Trump too freely. Newsflash: It's completely in keeping with the character. In 2016, Clinton got 85% of the vote in Boston. Throughout the series, Sunny has been an outspoken, irreverent, lifelong Bostonian. To borrow a phrase, get over it, snowflakes.
I love Marian Keyes' style. She's warm and witty and there are moments of such complete identification I either smiled or hurt when I read them. The Dublin/London setting charms me, too. (This is the only novel I've ever read with characters named Aoife and Manoj.)
BUT ... The ending seems rushed. After 500 pages of a certain pace, the acceleration of events kinda rattled me. And Lily! We're clearly supposed to like her, she may even be meant to be our favorite. But she's so passive aggressive, so idiosyncratic. I admit that whenever I saw a Lily chapter begin, I toyed with skipping it. I didn't, which is good because they always moved the plot along.
