The Black Book of Buried Secrets (2010) (edit title/settings)

• Rated 5 stars

“This companion to the popular 39 Clues series is less a novel than a compilation of lists, reports, and vignettes. It shares information that was delivered through the collectible cards and online game, rather than in the books, which is useful for those who didn’t play along. It also contains several short stories about Cahills past and present; the latter form a narrative about the time between the 39 Clues and the upcoming Vespers Rising. The hidden codes and extra background are fun, but it’s pretty obviously a hook for the next series. The only subtle aspect is the revelation about precisely how wicked great-great-great-etc.-grandpa Vesper was.”

THE BLACK BOOK OF BURIED SECRETS takes all the information gathered by the five branches of the family and stores them together in one book. Each branch, including the Madrigals, spill their secrets and some identities of their agents - past and present.

While it doesn't advance the story of the Cahill family, readers will enjoy uncovering more information about THE 39 CLUES series and its characters.

This is a great finale to the first series where all the material comes together. I loved how the authors are the real agents in this book - a great twist. I also loved reading about the hot spots of the various branches of the family, their history, the tricks and tools, and famous members.

The layout makes for a fast read and includes great pictures. ”
