I tore through The Faith of Beasts by JSAC, really loving the new universe they've developed. Very much looking forward to rereading TMoG, Livesuit and TFoB very soon and the show being developed.
I'm reading book 4, Children of Strife by Tchaikovsky and enjoying it thoroughly. AT has been my favorite contemporary author for the last few years based on how wide-ranging and prolific he is. I discovered AT by reading The Final Architecture series, which is still my favorite series by him. Honorable mention is his Dogs of War series, also amazing.
Last year I discovered China Mieville by reading Embassytown, the mindfuck storytelling and intelligent prose blew me away. That book still haunts me and twists my brain almost a year after reading it. I've never had a book that still makes me think and feel strange months after finishing it. Perdido Street Station was also amazing, super fun and original steampunk world. Very much looking forward reading the next two in that series and digesting more of his catalogue, I think he's my new favorite.
Also recently read The Prefect by Alaistar Reynolds, set in the Revelation Space universe and it's also fantastic, really good stuff. Stoked to finish the series.
As far DNF I was surprised I couldn't push through The Algerbraist by Iain Banks, I got bogged down on Jupiter just couldn't keep at it.
