Succubus Dreams & Succubus Heat, by Richelle Mead

The tables have turned on succubus Georgina Kinkaid. Something is sucking out her life energy while she sleeps, leaving her with bittersweet dreams in its place. At the same time there is a brand new succubus in town and Georgina is supposed to show her the ropes. But is Georgina in danger of being replaced in more than one aspect of her life and work? It’s all actually a bit of a nightmare. In mourning for her losses, a heartbroken Georgina is sent to Canada by her boss demon Jerome to help out another demon. But strange demonic politics are afoot and Jerome’s disappearance creates a dilemma for Georgina. A temporary loss of her abilities makes it possible to rekindle an affair with a former love, but what damage will it do to all involved? A strange alliance with a foe from the past restores Seattle to politics as usual, but big changes could be in store for our favourite succubus.
