Each of Emma Newman's Planetfall quartet explores a different aspect of the same overarching story of religious driven intergalactic migration. In Atlas Alone (2019), the fourth story centres on an elite gamer & their attempt to uncover & then take revenge for a crime against humanity. To say much more would ruin the plot for you, but as with the others, this is great, fascinating sci-fi, which has a great payoff at the end.
