Another fab Devils Set book

Have got hooked on Ember Casey’s Devil Set books!

Find myself lost in treasure hunting adventures, travel, mystery and a bit of romance.


It’s a nice mix of all of them

Final book in the series- although the author did hint at a possible 5th book about one of the other characters. A fun adventure for sure. 🏴‍☠️💍
