Bleeding Heart is a paranormal romance (the supernatural element stemming from alchemy). Type and Cross is a family drama, but at its heart, it's a love story. Both focus on the hero and heroine and whether they can reconcile their differences by the end.
I thoroughly recommend Lock & Key by Gordon Bonnet. The characters are three-dimensional, the plot is well-developed, and the settings are rich and tangible. If you love sci-fi, you don’t want to miss this novel. And if you’re new to the genre, this is a great one to start with.
