A Curse For True Love by Stephanie Garber
'Two villains, one girl, and a deadly battle for happily ever after'
This is the final book in the series. I probably needed to re read the first two before I dived into it as there was a lot to remember but Jacks made it worth it. Sugary sweet in places but shot through with poison and fun and romance. As beautiful as the cover.
From the back
Evangeline Fox ventured to the Magnificent North in search of her happy ending, and it seems as if she has it. She's married to a handsome prince and lives in a legendary castle. But Evangeline has no idea of the devastating price she's paid for this fairytale. She doesn't know what she has lost, and her husband is determined to make sure she never finds out . . . but first he must kill Jacks, the Prince of Hearts.
Blood will be shed, hearts will be stolen, and true love will be put to the test in A Curse for True Love, the breathlessly anticipated conclusion to the Once Upon A Broken Heart trilogy.
