A Fae Assassin's Binding

Kai doesn't make mistakes. He's killed lords, merchants, and traitors without leaving a trace. But when Celeste Brightwood walks in on his latest assassination, he makes his first error: he lets her live.Now they're bound by her botched protection spell, trapped within a foot of each other with no escape. Kai has three rules: trust no one, need no one, leave no witnesses alive. Celeste breaks all of them just by breathing. As they flee through the Fae Courts with hunters closing in, the assassin who should be her nightmare becomes the only thing keeping her alive. And Kai, who spent his life making himself a weapon, learns what it costs to be Fae again.Some bindings can't be broken. Some were never meant to be.This is the fourth book in the Star Crossed Fae series, but each book stands alone and can be read in any order.
