Although it starts off quite differently, by the end William D. Arand‘s first Cavalier’s Gambit novel bares a strong resemblance to Privateer’s Commission (which takes place in the same setting). The main difference is that the protagonist here is much more engaged with what’s going on and has a habit of “flirting” with most of the female characters he encounters.
The first of Jin Holland‘s Lost in Fiction novels starts off rocky. Much too rocky. The character actions are incredibly sketchy, the setting is questionable, and there are various (albeit admittedly minor) contradictions in the text. Had to drop it after the F-ranked protagonist somehow manages to solo a harpy nest with zero explanation or details.
