Sadly I was quite disappointed with this book. And just because it was not about what the cover and the synapsis and everything told me what the book was allegedly about. Judging from the cover ist should have been a book about Han's and Leia's relationship after episode 4 and maybe you could say it is about that, but they had almost no time together, and the time they do spend together was a little bit: "I cold take it or leave it, I really don't think it's that great spending time you." (Not a Quote but it could be). It would habe been a much better book if I would have been able to go in to this book with the right expectations like with a title like "After the Rebellion" or "The battle of ..." or "The start of the new republic" or something like that. 
I know that star wars is not typically super romantic but with such a book I think a little bit of romance would be appropriate,

not just that there is a proposal and a wedding

and nothing more. And I think there were one or two fade to blacks but I am really not sure because it were moments like "we were finally alone"-> End of Chapter.
All in all I love Princess Leia so much but this book was a miss for me and I would have enjoyed it more with either more romance or an entirely different focus of the book maybe event with a different title. That would make it clear that the focus is not the relationship but Leia's roll in building the new republic.
