Forged in Cursed Flames by Shari L. Tapscott

Lady Clover’s life suddenly takes a turn for the worse when she’s framed for necromancy by Princess Camellia. She and the princess both know she’s not a dark magic user, but little good that does Clover when Camellia disappears.
The kingdom is in turmoil over the abduction of their beloved princess, and Clover is determined to find her way into the rescue party—even if Henrik, the most handsome commander in all Caldenbauer and the man of her reoccurring dreams, is in charge.
He suspects Clover’s guilty.
Clover thinks she should have pushed him into the troll pit when she had the chance.
Once again, they’re at odds, but they have no choice but to play nice if they want to find Camellia—especially when they discover their mission will take them into the heart of Ferradelle, the High Vale elves’ territory.
They’re going to need a guide. Thankfully, they know an elf who just might help them…for a price.
