The Hollow Court

The fae are not a myth.
They live beyond the Hollow Woods, hidden behind ancient magic-and mortals know better than to enter.
Until Sera's brother disappears.
Desperate to find Rowan, Sera breaks the one rule she's spent her entire life obeying and enters the woods. Instead of finding her brother, she finds Caelen, the High Fae King.
Cold. Powerful. Dangerous. Attractive, and he knows exactly where Rowan is.
Caelen promises to bring him back, but only if Sera agrees to a binding deal with him.
Now trapped in a world where promises have consequences and nothing is given freely, Sera begins to uncover secrets about the four courts-and the ancient Heartwood that connects them all, and the deeper she ventures into the fae realm, the more she realizes something terrifying:
The Heartwood didn't bring her there by accident.
