A lot of guys claim to have hot girlfriends. David Fraser has one who actually breathes fire.

Rose Drake is a Dragoness in Human form, come to Earth for three years to soak up the local energy and increase her chances of having happy, healthy, baby hatchlings when she goes home. In exchange for his time and energy, David's body and love life both undergo extreme makeovers. It sounds like the deal of a lifetime.

Fate doesn't let David and Rose off so easily. A friend of theirs is murdered, their homeowner's association starts harassing them, and they have to complete a quest for an Elven sage in order to stop a genocidal Unicorn from turning Earth into a radioactive wasteland.

After all, when you're dating a Dragon, you're already a hero. It says so in the fine print.
