What's the Story?

What is THE ASSASSIN'S CURSE -- and who are the shadowy figures hell-bent on wiping out the royal family of France? Seventeenth-century English teens Christopher, Tom, and Sally and the brave pigeon Bridget, tasked by Charles II himself, are soon on their way to the court of Louis XIV to find out. It all seems to have something to do with the Knights Templar. And a famous painting. Also a poem written in cipher. Our heroes face many dire perils en route to a conclusion that suggests their troubles are just beginning.

Is It Any Good?

Our review:
Parents say ( 2 ):
Kids say ( 1 ):

Author Kevin Sands delivers another harrowing, hilarious, heartrending page-turner set in the 17th century, this time with his teen protagonists sent to spy on the court of Louis XIV. The Assassin's Curse delivers a bit about deciphering codes, the history of the Knights Templar, and just the right chemicals for dissolving gold. There's lots of historic detail, suspenseful intrigue, and opportunity to cheer the appealing heroes -- who need all the help they can get.

Talk to Your Kids About ...

  • Families can talk about The Assassin's Curse as historical fiction. Do you think it makes history more relatable if you can see it through the eyes of a fictional character, or would you rather stick to the facts?

  • If your family originally spoke a language other than English (like Sally's family in the story), and then started speaking English, do you still speak the original language, or have you forgotten it?

  • Do you think cemeteries are really interesting, or just creepy?
