Dragon Chosen by Mac Flynn

Rose Dumont was just your average office worker toiling away at her day job. That is, until she found herself captured and carried through a portal into a different world. She was one of a group of women, and their kidnappers informed them that one among their number would be chosen to be the bride of the local dragon lord.
Rose wasn’t going to wait around for that to happen and she manages to free herself. She flees into the woods only to stumble upon a dark manor house. Unfortunately, she soon realizes that she’s walked into new trouble, for the house is owned by the very dragon lord she sought to escape.
The handsome Lord William Thorn is an ancient creature desiring a mate, and Rose is just the person. She soon finds herself falling for his gentle eyes and sensual touch, and one thing leads to another. Before she knows it she’s neck-deep in magic and intrigue as her unlikely lover and she confront a venomous foe intent on stealing Thorn’s greatest magic: his immortality.
