Review

A gender-switched reimagining of The Count of Monte Cristo, A Promised Vengeance follows Elodie Dantès, a heroine who refuses to stay powerless in the face of betrayal. Watching her transformation from someone wrongfully imprisoned to someone who takes control of her fate and seeks vengeance was great, even though I sometimes struggled to understand her actions. She doesn’t always choose the moral high ground, and she’s definitely a morally grey protagonist, but I feel like that made her story even more compelling, as she learns the cost of seeking vengeance.

The relationship between Elodie and the priest was one of my favorite parts of the novel. Their connection felt so sincere and gave the story a rare softness amid all the darkness and anger, much like the imprisoned pair in the original story. The priest becomes a true friend to Elodie at a time when she needs it most, and it was very touching, especially after she faced so much betrayal and then a significant amount of isolation.

The first half of the book moved at a slower pace than the second half, which made sense contextually. There was definitely a build-up to the final confrontation and Elodie’s journey toward exacting justice. However, the ending felt a bit rushed, especially after so much buildup. I think I expected to see Elodie face more challenges than she did, and I wanted a little more groveling from her love interest. Even so, her journey was powerful, and I ended up enjoying how everything played out.

A Promised Vengeance is an empowering story about reclaiming one’s power, confronting betrayal, and deciding how much of yourself you are willing to lose in pursuit of justice. I always like Sara B. Larson’s stories, and this is no exception.

Thanks to NetGalley and Jumelle Press for providing me with a copy of the book. All thoughts are my own.
