The Princess and the Scoundrel by Beth Revis
Set just after the end of Return of the Jedi, this new novel covers Han and Leia's wedding for the first time in the new canon. There's more to the story than that, of course, as the newly-married couple end up on a whole new adventure despite their attempts at a relaxing honeymoon.
The book is also something of a tie-in to Disney World's Galactic Starcruiser immersive Star Wars experience hotel, with both taking place on the Halcyon luxury vessel.
