The Alchemist's Apprentice

The crown prince is dead. Now his exiled brother is heir to the throne, and the poisoners next target. And the only girl who can keep him alive is the reason he was banished.
No one at court notices the royal alchemists apprentice until the crown prince collapses at the midwinter banquet and her master is found dead before dawn. Suddenly Keryna is the only person in the palace who can name the poison, and the only one who can trace it back to the killer before they strike again.
Prince Valtteri never wanted to come home. The palace holds nothing but bad memories, and half the court would sooner see him dead than crowned. His forbidden magic flares whenever hes threatened, and the only thing that steadies him is an apprentice who handles it like any other volatile compound.
Working at his side is dangerous, but wanting him is worse. Every kiss is another lie, told to a man who has already lost everything once to a secret.
The most dangerous reaction in the palace isnt brewing in her laboratory. Its the one that will explode when Val learns the truth.
