Solid 4 stars. 
 I've never been a chronological reader; I just pick up whatever book that catches my fancy. When I read It Happened One Autumn for the first time, I had no idea what I was getting into--I started the series with it. The description had simply intrigued me, since I've always been a fan of the "stoic-hero-cracks-under-the-heroine's-spell" trope, a la Mr. Darcy and Elizabeth Bennet. 
 But this time around, after re-reading the series, I find myself having a totally deeper appreciation of the book, primarily because I saw how Marcus' character developed since the prequel. In Again the Magic, he was the protective brother whose patience and understanding knew no boundaries. In Secrets of a Summer Night, he was the loyal friend who would risk his neck to save those he cared about. 
 And in this book? He was the perfect Mr. Darcy--albeit the more wanton and less self-controlled version. Terribly frustrating, slightly conceited, and logical to a fault, he thought he had his life all planned out: fulfil his duties as Lord Westcliff, find an amiable wife, beget sons, and that's it. Well, that is, until he met the one woman who turned his carefully laid plans on its heels--Lillian Bowman. 
 I remember hating Lillian, but I'm glad to see that she wasn't nearly as irritating as I thought. Yes, she was far from being a stellar character. Yes, she had her TSTL moments. And yes, she was frustrating and illogical with her refusal to marry Marcus despite of being thoroughly shagged by him. But that's judging her in isolation. 
 If you pair her up with Marcus, you'd see that she's simply perfect for him. She brought him back to Earth with her well-deserved set-downs. She provoked him like no other woman did, and made him feel things. She made him get off his self-created pedestal and see himself for the mortal that he was. 
 In short, she was everything he needed. And I think Lisa Kleypas captured that nicely in Marcus' proposal: 
 "If you won't marry me for the sake of your own honor, then do it for the sake of everyone who would have to tolerate me otherwise. Marry me because I need someone who will help me to laugh at myself. Because someone has to teach me how to whistle. Marry me, Lillian...because I have the most irresistible fascination for your ears." 
 While I am thoroughly convinced that Lillian and Marcus belonged to each other, I just couldn't help but feel bad at how Sebastian was treated here. Okay, okay, so he deserved getting his ass whipped. Fine. But I'm an intensely loyal fan of his and Evie's, and I couldn't help but cringe at some parts of this book. Especially when he flirted with Lillian. Ugh. 
 Overall, though, I really loved this. Would I re-read it again in the future? Sure. Would I recommend it? Hell, yes.
