Tithe

Do you believe in faeries? Not the soft, gentle kind, but the sinister, feral kind ~ the ones that wreak havoc on everything in their path...
Sixteen-year-old Kaye is a modern nomad. Fierce and independent, she travels from city to city with her mother's rock band, until an ominous attack forces them back to her childhood home.
To the place where she used to see Faeries.
They're still there. But Kaye's not a child anymore and this time she's dragged into the thick of their dangerous, frightening world. A realm where black horses dwell beneath the sea, desperate to drown you… where the sinister Thistlewitch divines dark futures… and where beautiful faerie knights are driven to perform acts of brutal depravity for the love of their uncaring queens.
Once there, Kaye finds herself an unwilling pawn in an ancient power struggle between two rival faerie kingdoms ~ a struggle that could end in her death…
