An Unsuitable Heir by KJ Charles

3.5

I'm of two minds about An Unsuitable Heir. At this point I can say with confidence I could never hate a KJ Charles book, her writing is just too charming to ever hate. But I can't deny there was something missing about this final installment in the Sins of the Cities series. 

But let's start with the positives. Pen and Mark were as charming as any KJ Charles couple. I appreciated Charles' exploration of disability and especially gender identity through their love story. Charles detailed exploration of non-binary identity and the complexities of gender fluidity through Pen was much appreciated. Seeing someone find an affirming community and express the truest version of themself proudly is always heartwarming to see. And I think the framework of a romance is especially meaningful avenue for this story because we get to see Pen find someone who affirms their gender unconditionally. 

My big problem with this story was that Pen and Mark's romance felt secondary to the mystery plot. Our two leads spend significant chunks of the novel in completely different locations and much of our page time was dedicated to either unravelling the tangled web of this inheritance plot or exploring Pen's relationship to the prospect of becoming an earl. 

Foregrounding the mystery plot in this book only really served to highlight the weaknesses of its construction. To be fair these weaknesses, like an excessive convolution and being generally unsuspenseful, were present in previous installments. But because those novels were primarily romances I wasn't really bothered by their meh mysteries. An Unsuitable heir in contrast heavily leans on its mystery so its anti-climactic resolution left me cold.

Honestly I don't want to rag on An Unsuitable Heir too much. It honestly had some lovely moments. Pen and Mark were cute. And outside of some minor plot holes that irked me
(If all the evidence that Edmund married Emmaline and had a son with her were destroyed wouldn't Edmund's son with his second wife regain his inheritance as the earl rather than Tim)
. But outside of that I had fun.
