At the Edge of the Otherworld: A Celtic Urban Fantasy (Rise of the Celtic Gods, #3)

From a USA Today bestselling author comes a tale of magic, myth and Irish music.
The battle is upon them, but Maura must decide who she is and if she deserves love, if they are all to succeed.
Maura has had enough of the gods seeing her worth and usefulness only as Morrigan, the war goddess. Even Finn, who she might count as a close friend on her best days doesn't understand. And now that they are all assembled and tasked with retrieving the two treasures to fight Balor, Maura leaves in a fit of anger. Her anger takes her across the sea to the middle of hot, dusty America where she makes an odd set of friends, including Raven, who is other than he seems.
Finn finds himself missing Maura more than he thought possible, and in the midst of helping Smithy, Saoirse and Luke cope without Maura's help, he finds he has his own demons to fight. They are a motley crew facing the biggest challenge-to collect the treasures and lure Balor back to the Otherworld where the final battle will take place and Balor killed. To succeed they must all come to know and understand who they truly are. To fail would mean not only their deaths, but the death of Ireland.
