When Aunt Grace dies, she opens up a clue to a secret that can make or break the world. Each member of her family is offered two million dollars to take as an inheritance and walk away…
or…
you can turn in the bank voucher for the 2 million and instead get a clue to something…. amazing. Something that can make you powerful and probably save the world.
Most of the family takes the 2 millions dollars… after all Grace was old and seriously may not have been in her right mind. The 2 million is a solid deal.. the clue? Not so much.
Yet 7 families do take the clue…. many of them already wealthy are greedy for the thought of power…. but for Dan (11) and Amy (14) Cahill they really don’t see what they have to lose. Warded to an unloving Aunt Beatrice after their parents were killed, Beatrice (Grace’s sister) treats the kids like dirt. The clue…could provide freedom and adventure.
They take the clue.
Soon the siblings as well as the very strange and power-hungry members of their family are on the hunt of a lifetime. They follow the historical trail of Ben Franklin to find the next clue, with Amy’s book smarts and Dans math smarts they can and do go far but not without trouble from other family and others who they thought were allies, who want the treasure for themselves.

This book has interested me since it was released…. probably because it is more than a book. The book includes a website, trading cards, and is really part of a 10 book series penned by different authors. You can even log into a site and become part of the hunt. Being a big fan of movies like Indiana Jones, National Treasure, Jewel Of The Nile…
yeah… I was hooked and Scholastic, you are brilliant.
I listened to this one on audio and by now I am starting to feel I have Rick Riordin’s number. His characters from what I have picked up on from Percy Jackson and the Olympians as well as Red Pyramid have given way to characters of youth of fantasy and intrigue.
The audio book was a joy to listen to. As an adult it held my interest and I loved the historical information sprinkled through the book as the siblings uncovered the clues within the clue. Even I learned a few things about Benjamin Franklin that I did not know. 🙂 As a middle grade reader, I think these books would be devoured.
I love that many authors worked on these books together, each adding their own personal flare. I just love that!
