Read the first 4 volumes in R Fabbri's series about Alexander's Successors and their wars, called Alexander's Legacy; definitely interested in upcoming volume 5 tbp later in 2023: my Goodreads minireviews for all below
1: To the Strongest
Presented from multiple viewpoints, the story of roughly the first 3 years after Alexander's death, dominated by the regent Perdiccas who has Alexander's ring but not his full endorsement and who doesn't have the best political mind either, though his martial abilities are unquestioned. Excellent stuff, gripping and fascinating
2: The Three Paradises
The immediate sequel to the first volume, this one covers the years of Antipater's regency and the ascension of Antigonous. While the fracturing started, there are still two kings (true, one is a half-wit and another a young child and not a pure Macedonian either), so the regent still acts in their names, but of course, others may claim the same on various pretexts. Still very entertaining
3: An Empty Throne
The third volume covers the rise and downfall of Olympias, Alexander's mother who uses that Antipater shockingly leaves the regency to his second in command rather than to his oldest son, while technically not having the power to bestow the regency on anyone, so opening another huge can of worms. Unfortunately despite advice from all her councilors, Olympias is set on revenge on those (and there are many) who belittled and minimized her. In Asia, Antigonous continues his ascension, as he holds the most armies and more and more, that, rather than any legalistic arguments, is what actually counts
4: Babylon
Maybe due to reading the first 4 installments of the series one after the other, or maybe due to the fact that some of the most interesting characters left the scene and the new ones are not at their levels, while the "not on my ar.." expression of Antigonous, kind of started wearing thin, but this while still interesting is the weakest volume so far. Essentially what is known as the 3rd Diadochi war with Antigonous (biggest army, wealth, and interior position) against most everyone else (scattered in various places) who are by and large orchestrated by Ptolemy of Egypt; Antigonous wants it all, the others just want their kingdoms, though for now they still all act in the name of the regency as one of the kings is still on the board and as Alexander legitimate son, he is still difficult to kill without encountering the various armies opprobrium, but everyone kind of knows the child is not going to survive for long as nobody really cares about him anymore with his main protectors all dead
