Start with Descender, Vol. 1. There is no alternative order and no shortcut: this is a single continuous story told across six collected volumes, followed by a three-volume sequel series. Read the numbers in sequence and you are done.
The one decision worth making in advance is whether you are committing to nine volumes or six. Descender, Vol. 1 through Descender, Vol. 6 are a complete story with an ending. Ascender Vol. 1 onward is a sequel set a decade later that deliberately swaps science fiction for fantasy, and readers who loved the first series are split on the second. More on that below.
What it is
Giant machines appear over the Nine Planets, cause enormous destruction, and vanish. In the aftermath, robots are hunted and destroyed across the galaxy. Years later a companion android called TIM-21 wakes alone on a mining colony, and it turns out he is connected to the machines in a way that makes him the most valuable object in known space. Jeff Lemire wrote it; Dustin Nguyen painted every page in watercolour, which is the reason to buy the physical volumes rather than read it on a screen. The art is the argument for the book — soft, washed, and constantly at odds with what is actually happening in the plot.
The six Descender volumes
Descender, Vol. 1, published as Tin Stars, sets up TIM-21 and the crew assembled to retrieve him. Descender, Vol. 2 and Descender, Vol. 3 widen the political picture and fill in the history, including a long flashback sequence that most readers find the strongest material in the run. Descender, Vol. 4 and Descender, Vol. 5 accelerate hard, and Descender, Vol. 6 — published as The Machine War — ends it. It is a real ending, not a stopping point, though it also plants the seed for what follows.
Ascender, and the genre swap
Ascender Vol. 1, Ascender Vol. 2 and Ascender Vol. 3 pick up ten years later in a galaxy where magic has replaced technology and a sorceress rules what is left. This is not a tonal drift; it is a stated, structural change, and Lemire has been open that the second series was conceived as fantasy from the start. If what you liked about the first series was the hard-edged science fiction, you may not want the second. If what you liked was Nguyen's art and Lemire's habit of building a story around a child and a machine, you will. Either way it has to be read after Descender — it assumes all six volumes.
Editions
The trades are the standard route and they are numbered plainly. Deluxe and omnibus hardcovers exist that collect several volumes each under their own numbering, so pick one scheme and stay in it — mixing trades with collected editions is the reliable way to buy the same issues twice. Note also that our catalogue records these under bare volume titles rather than the published subtitles, which is why the list above reads as numbers.
Honest warnings
The first volume is the weakest. It spends a lot of pages on setup, the cast arrives faster than it can be distinguished, and several characters who matter later are barely sketched. If it feels thin, keep going to the second volume before deciding. The other common complaint is that the plot leans on a small number of coincidental reunions across an entire galaxy; the series is not interested in disguising that, and readers who need their space opera plausible will notice.
Where to stop
The end of Descender, Vol. 6 is a legitimate stopping point and leaves nothing dangling that you will resent. Continue into Ascender only if you want the fantasy version. More comics reading lives on Discover.
