I finally finished this behemoth! The fact it took me so long should not be taken as a diss on the book - it's actually quite, quite good.
It felt like a return to form for Hamilton (I didn't overly love the Salvation trilogy, though I own the hardbacks for their drop-dead stunning covers....) He dialed the worldbuilding up to 11 (the worldbuilding in the Night's Dawn trilogy being pegged at about 17 ), while also crafting a final third packed with fast-paced action and edge-of-your-seat suspense. Reminded me of Pandora's Star/Judas Unchained, which is my favorite PDF tale.
Perhaps most importantly, it brought the game world of EXODUS (website: https://www.exodusgame.com) to vivid life by letting the reader live in it for a thousand pages. This made me even more excited to play the game, which is the highest purpose of every game tie-in novel.
