I just finished reading Star Wars Bloodline and I LOVED it. This has to be my favorite Star Wars novel ever.
Bloodline is all about what Princess Leia is doing prior to The Force Awakens. The novel starts 6 years prior to The Force Awakens and is considered canon.
I really thought the novel took place longer than 6 years before The Force Awakens but the canon says otherwise. It felt like it was 10 plus years.
The beauty of the book is that it delves into Galactic Politics, and thus shows the beginning of the First Order, and the Resistance, and shows the motivation behind people supporting both factions.
Luke and Ben are only mentioned briefly but Han appears in a couple scenes.
I loved the supporting characters in the novel such as Senator Ransolm Casterfo, Pilot Joph Seastriker, and Pilot Greer Sonnel.
I highly recommend that you give this one a read as it was awesome.
