Based on recent reads (will edit if I remember more):
* "Daros" by Dave Dobson https://www.amazon.com/Daros-Dave-Dobson-ebook/dp/B0946C153P - At the heart of the plot was a powerful artifact with different groups vying to gain access for different reasons. The humor, especially the chapter titles, worked well for me. Features mysterious creature, a sassy AI, a fast paced plot with good amount of action, etc.
* "Dim Stars: A Novel of Outer-Space Shenanigans" by Brian P. Rubin https://www.amazon.com/Dim-Stars-Novel-Outer-Space-Shenaniga... - Fun and filled with humor that had me laughing almost every page, especially enjoyed the slice-of-life feel in the first half of the novel
