One curse. Two sworn enemies. Thousands of lives in the balance.

Ash, dried flowers, and a drop of blood: Remy has all he needs to avenge his brother's death.

Five years ago, interstellar pirate Idrian Delaciel ordered a withering - a death curse - cast on Remy's brother, costing him his life. Now, Remy is ready to return the favour. Only when he casts the withering, it also rebounds onto him.

The implications are unthinkable - that Remy is fatebound to his brother's killer.

The only way to slow the curse is to close the distance between them, so Remy infiltrates Idrian's criminal crew, hiding his identity as the witherer. But Remy quickly learns that Idrian is the sole provider of life-saving supplies to thousands of innocents. And if he dies, they will perish with him.

With more at stake now than just revenge, Remy must find a way to break the curse. Too bad for him - the only way to stop a withering is to kill the witherer.
