Introduction to, "Gift of Sight," by Ms. Chartel Amos. Here's the back-story:
When the young Faidh (Gaelic for Seer), Ellen Floyd, is summoned before the Norse Gods of Old, she doesn't expect to have her gift challenged.
Nor does she expect to have her life turned inside out . . . Cheyenne Hinds is the first and only Valkyrie member of the FBI SOTF (Supernatural Occult Task Force) Division. When she and her partner and lover Loren Allen receive a call sending them to a crime scene in the middle of the Mohave Desert she realizes someone or something is killing off her kind.
Investigating the case she discovers her families twisted, dark, hidden past may be the connection to so many paranormal deaths. As she tries to piece together the clues a danger unlike any she's ever known draws closer, until all that stands between Cheyenne and death are three strange and mysterious Valkyrie who have been in protective hiding all across Euro-America.
