If you want the story of why Leia Organa left the senate of the New Republic to found the Resistance, and how she first found out about the threat of the First Order, this is the book for you. I read this book over the New Years long weekend while also moving for the second time in a couple of months, and it was just the kind of book that I needed in that scenario; a world and characters that I was already comfortable and invested in and competent writing that didn't ask too much of the reader.
The writing in this book is not groundbreaking, and the plot isn't revolutionary; Senator Leia Organa uncovers corruption, both in the senate and in the worlds that the senate is attempting to govern, a vast conspiracy that in the end turns out to be perpetrated by a new paramilitary group that is just now starting its climb toward power: the First Order. Considering where this book sits in the new canon timeline, a little before The Force Awakens, that isn't surprising. But the writing and character work that get us there are solid, and there are several characters that are introduced in this book that I got attached to by the end of the book.
I would recommend this book to anyone looking for background on the resistance, Leia, or the politics of the New Republic. It's pretty good, and worth a read! Just don't go into it looking for something groundbreaking.
