Books in the Lost Ancients series

A long-lost elven kingdom, body-swapping ghosts, walking weapons of mass destruction... Archaeologist and part-time bounty hunter Taryn St. Giles has had a Very. Bad. Year. Ever since she and her trio of singing, drunken faeries started digging into the mysteries of a certain handsome elven lord, she's been up to her nose in explosions, slavering monsters, and assorted other dangers. Now Taryn and Alric, their friends and more than a few enemies are racing across the desert to find the last pieces of a lethal relic so they can save their world and finally share a quiet pint of beer. But some secrets are buried deeper than a millennia, and this time, Taryn might not escape unscathed. Actually, she might not even be Taryn anymore...
