Heart of a Duke Series Guide
I am continuing my deep dive into Regency Romance on Kindle unlimited with Christi Caldwell’s Heart of a Duke Series. This is her first series and occurs prior to the Scandalous Seasons Series I have a whole other post about. Technically all of Christi’s books are connected by at least one character who crosses to another book and then on and on. But I did split my guides between those two series which seem to be a natural break. Below you will find the books in order with main characters and additional characters with the books they cross over to. If I miss any crossovers, don’t hesitate to let me know! I hope you find this guide helpful!
