A brand new adventure from the world of The 39 Clues!

For 500 years, the Cahills have been the most powerful family in the world. For 500 years, they've protected the source of their power - the 39 Clues. And for 500 years, they've kept their secrets silent. Until now.

This extraordinary stand-alone novel cracks open the Cahill vault to tell the story of the most coveted piece of artwork in the world, a masterpiece that has been the target of seven separate theft attempts: Jan van Eyck's altarpiece at Ghent. OPERATION TRINITY chronicles the first Vesper attack on the altarpiece in the 1600s, then jumps to WWII and young Grace Cahill's desperate bid to save the masterwork from the Nazis. The final piece of the novel tells the story of Ian and Natalie Kabra's first solo operation and features an 11th hour appearance by Grace Cahill on her final mission.

History will never be the same.

  • 5 out of 55 out of 55 out of 55 out of 55 out of 5 Chris | 2/8/2014

    " I enjoyed how we were able to get to know Grace better as well as see that the tension and uncertainty that Ian has regarding his mother began even before the clue hunt began. I am still enthralled by the fact that so many authors can write one series so seamlessly. "

  • 5 out of 55 out of 55 out of 55 out of 55 out of 5 Luci | 2/8/2014

    " It was an exciting book that kept me wanting to read more! "

  • 4 out of 54 out of 54 out of 54 out of 54 out of 5 Melissa Sodano | 2/1/2014

    " Despite the fact that this book does not chronologically fall within the 39 Clues, this book provides some interesting back story. Riley follows a particular work of art by Jan Van Eyck through three (non-consecutive) generations of Cahills, each of whom must protect it from the Vespers. A fun read, though you don't have to read it in order to know what's going on in the rest of the series. "

  • 3 out of 53 out of 53 out of 53 out of 53 out of 5 Rishi G | 1/10/2014

    " I was really excited when I started reading this. I was really disappointed because from page 3 to page 43, the whole story was so boring. When the author started Grace's story, it got a little exciting but eventually it got boring again. The whole book doesn't have a story at all!! I have read his rapid fire series and I was amazed by the story in it. So I thought operation trinity would be a good book. It turned out to be bad. It's a ok book. "

    " I like these books but it is getting difficult to keep track of all the series that are off-shoots from the original one. :) "

  • 2 out of 52 out of 52 out of 52 out of 52 out of 5 Jim Short | 12/2/2013

    " Very scattered plot. I think they are trying to keep the connection with the currently known characters but they could just write the story with any character from history. "
