Not sure what to say about this. I was SUPER psyched to see how things finally shake out between these three ladies and their revengey plans. Mid-book 2, they sort of gave up on the idea of Revenge, but then with the whole Rennie thing and the Mary reveal, we have ourselves a new (and extremely scary) villain. 
 So I *liked* it, but there's an epilogue that wraps things up in a way I'm not super a fan of. I don't need to know what these crazy teens do post-college, and while it makes sense to me as a grown-up, I'd rather it all end with the book equivalent of a dance montage, not real-life grown-up facts. 
 THAT SAID, Jenny Han writes the best descriptions of foods and desserts (assuming she wrote the Lillia scenes, where all the food action is, because there's also great food porn in Han's other books), and Siobhan Vivian writes sassy Kat super-well, and the trilogy is great fun. Wouldn't be surprised to see this pop up on The CW as a PLL-meets-GG new TV series. Which would hopefully have a slightly different ending.
