I read this last night (all of it) and I've been thinking about it since then. I can't get it out of my head. I luuurved this trilogy. Hmm, I think the five stars are for all of it and not only this book. 
 What I liked most about this one particularly: it was intense, well written, the characters captivating as always and just with the right amount of drama (considering). 
 What I missed in this book that actually was present in the other two: THEM, SOPHIE. I mean, the first two books are so clearly about Sophie and her family, and this one is so clearly about the war... It didn't bother me at all while reading, because it was fascinating and I really like historical fiction... But, you know, what captivated me from the first book was that while nothing much was happening half of the time, it was really interesting -- I mean, there were entries almost every day and Sophie always had things to tell, I loved that and I thought it said much about the author's ability. But this book happens so fast. I felt like the Simon incident was 2 days ago and actually 2 years had happened!!! I understand that during WW2 Sophie's life was not as interesting and that most days she just went to work and cooked for her and Veronica, but, I think she could have made cool entries anyway. I understand that WW2 swallowed everybody's lives. I don't know, I'm not complaining, it's just that I missed characters. Simon (and he's my least favourite, tbh) disappeared completely for like 2 years, and Veronica was conveniently in Spain too much (I mean, really, Spain was so inconsequential to WW2). 
 Anyway, I loved it, ok. It's not only very emotional and well capturing of its characters psychology, but it's truly intelligent and comprehensive of the times. 
 Now, my complains, with spoilers: (view spoiler)[I'm sorry but I CAN'T GET OVER TOBY. I LOVE HIM. And I'm so angry at the end he gets. I'm not even complaining of the Resistance fandango and the bomb and all, I mean: AFTERWARDS, IN ENGLAND. I really liked the idea of a marriage between Julia and him. I love them as friends, and I thought that their marriage allowed them still to find ~~true love. Yeah, I imagined like two best friends having children but having sex with other people. AND THAT MADE ME HAPPY. But adding Simon to the mix? omg that is so DECADENT. I suspected something when Sophie says that Simon is so complicated that he would need two people to make him happy, but WHAT. He hates Julia and I don't like them together, and I like him with Toby, but I wish Toby were enough for him? Also, what is this child Davey? I sincerely hope he is not the heir of the throne. MY GOT. How I cried at the end of the book when Toby signs the message with: KING TOBY. Omg, so emotional. 
 Complain number 2: RUPERT I LOVE YOU BUT. BUT. HOW. I mean, I liked him from the beginning, and I always wanted him to end with Sophie. But the way she realised she was in love with him! Nooo! I wanted more development. I wanted to take pleasure in their courtship and the does-he-really-like-me, do-I-really-love-him, is-that-love? It was so sudden. But yes, Rupert and Toby are my favourites, I adore them. 
 Other complain: I know it's quite unimportant but: why did she give Aunt C such a violent death? couldn't she die from a bronchiolitis or something? 
 Other complain: WHAT WITH HER MUM'S DIARY????????? 
 Last complain before I gloat over what I liked: The epilogue? I wished it was way into the future. The fact it's done 4 years from the ending is sad: so many things can still change! Sophie is 28! I feel that if you do an epilogue you should be able to tell: and those were the consequences of all this. But I think the consequences are still happening? I don't know, that is just me rambling. 
 Now, what I loved: everything else and everybody. Sophie, Veronica (she's marvellous, and I love her even though sometimes I wanna punch her in the face, and her and Daniel omggggg), Henry!!!, Julia!!!!, my boyfriends Toby and Rupert, the sexy Colonel (HE IS SEXY), I loved them all. (hide spoiler)] 
 Omg this review was like, so teen.
