I liked Sacked but didn't love it as much as everyone else, I think. There were plot elements that didn't do it for me, especially at the end. But Frederick is great at fast-paced sexy-flirty-fun stories so I knew I'd read this sequel as well, though I was hoping it would be Jack or Ty's story. Matty and Hammer didn't make much of an impression on me in book one and I'm sort of sorry the series turned in this direction-- of going through the football team members as opposed to sticking with the brothers. That meant there wasn't much of Ellie and Knox in this one either. 
 But all that said, Lucy and Matty are both great characters, with interesting interests (the mock trial subplot was great!) and complicated lives. And Matty is actually nice to her, which is all too rare in these books (that was true of Knox in Sacked too -- there are no big mistake and big forgiveness scenes that can be so hard to pull off). Overall the book is smart and sexy so it's worth a read, but not all of it works (for me). 
 P.S. I agree that Ace is a real problem, as other readers have said. It wasn't just that he was such a total asshole that it was hard to believe Lucy was ever friends with him. It's also that he epitomized all the double standards in most NA sports romances: that it's okay for these jocks to sleep around and treat girls like shit but not okay for the heroines to behave less than perfectly, that it's okay for the guys to do this as long as they meet their girl and get reformed. And that's teeth-gnashingly, maddeningly wrong. I mean, it's such a given in these books that it's hardly worth complaining about but Ace's behavior makes the whole problem much more obvious because (view spoiler)[it turns out to be *intentional*. He wants to screw around with "sluts" and then settle down with the "good girl" who's been patiently waiting for him to come around. (hide spoiler)] Of course he doesn't get what he wants, but it makes the whole fantasy of the reformed bad boy much harder to believe....
