A few pages have gotten out.
Some guy claimed on Reddit (/r/StarWarsLeaks) that he had a copy and clearly he is telling the truth.
He said there was no Luke or Snoke in the book. The Table of Contents confirms it.

-----------------------------------------------
Some pertinent information from the pages:
Han became the husband to a influential New Republic politician.
Han is a family man.
There was a "profound tragedy" of some kind.
Han returned to his old life.
Han still uses his old DL-44 blaster although newer models have come and gone.
Maz is a smuggler.
Maz has survived and thrived in her long life.
She has an affinity for The Force, knew Jedi, but never walked that path herself.
Used her knowledge of The Force to keep herself out of danger.
In her centuries of travel, Maz has collected countless trinkets and treasures, not to sell but to protect.
Maz believes a relic from the past may someday make a difference in the future.
Lor was an explorer for decades.
Lor retired to live on Jakku.
Lor gives some information to Poe Dameron, but it is clearly not the lightsaber.
Lor is not Force-sensitive.
Lor was a follower of the Church of the Force.
It was a group of loosely affiliated worshippers of Jedi ideals. (Are the Knights of Ren the opposite of this?)
Hux's father was a high placed official in the Imperial Academy back in the day.
Hux's father fled into the Unknown Regions after the Empire signed the Galactic Concordance. (The Galactic Empire surrendered to the New Republic)
Hux believes it is his destiny to be given a chance to sit on the throne that is the galaxy.
Hux's experience in warfare is entirely theoretical.
Kylo has little respect for Hux as a warrior.
Hux and Kylo engage in a tense competitiveness for the attention and approval of Supreme Leader Snoke.
Hux has little understanding of or patience for the mystical side of The First Order which Kylo Ren represents.
Hux is the commander of the Starkiller operation, able to order its use - pending Snoke's approval.
Starkiller base is located in the Unknown Regions.
The First Order has been amassing a power that violates the treaty restrictions of the armistice.
It is the sun-targeting Starkiller weapons platform.
The device has the unique characteristic of being both a planet based and interstellar weapon. (So it is as rumored. The laser fires and can travel through space like a starship right to its target.)
Starkiller base is the largest known deployment of First Order military forces.
However, it is not considered the headquarters as Supreme Leader Snoke keeps his command center mobile.
