The next installment in the New York Times bestselling Sworn Soldier series, featuring Alex Easton investigating the dark, mysterious depths of a coal mine in America.

Alex Easton does not want to visit America.

They particularly do not want to visit an abandoned coal mine in West Virginia with a reputation for being haunted.

But when their old friend Dr. Denton summons them to help find his lost cousin—who went missing in that very mine—well, sometimes a sworn soldier has to do what a sworn soldier has to do…

Alex Easton is back and this time they’re traveling to America to help out Denton, who we might remember from the first book in this series. Be warned, if you are claustrophobic or have an issue with caves/mines, this one might not be for you – since a lot of the book occurs in a mine, there’s a lot of descriptions of tight spaces.

As with the previous books, Alex and Angus journey together to help figure out what is going on in the Hollow Elk mine. Alex’s internal and sometimes external commentary on America and the situation is hilarious and as always their voice is unique and clear. I really enjoy the characters that Kingfisher crafts in this series, not just Alex and Angus, but the supporting characters too – they all have their own distinct voices, which can be hard to keep consistant.

I don’t know if more installments are planned in this series, but I would definitely pick them up if there were, I would love to see where Alex’s travels take them next.

Happy reading!
