A Clash of Crowns [EPUB ebook] 

After surviving three impossible tasks, Ash Van Camp and Idona’s Allies find themselves one step closer to slaying the Dark King. But, the capture of one Ally provides them with a challenge far greater than anything they’ve endured to date.

Ash is willing to do anything for the people she loves, even if that means enlisting an enemy’s help and risking the respect of her fellow Royals, and her fellow Allies.
