Synopsis

The epic finale to the Chrono Explorers series. Every moment has been leading here.

Two years ago, four teenagers found a mysterious metallic disk in a forgotten storage room. It changed everything.

Emma, Leo, Riley, and Mia have jumped through history, outsmarted ancient conspiracies, survived futures that shouldn't exist, and kept the timeline from unraveling at the seams. They have faced impossible choices in every era, lost things they couldn't get back, and found themselves becoming people they never expected to be.

Now the clock has run out.

The Convergence is coming: a once-in-all-of-history moment when every timeline intersects, and the hidden war between the Keepers and the Architects reaches its final hour. The team has forty-eight hours to prepare. Four anchor points to secure. One failsafe to activate. And a cost none of them have fully calculated yet.

The Endless Hour brings the Chrono Explorers home, through battle, sacrifice, impossible reunion, and the truth that the most extraordinary adventures are the ones that change who you are.

This is the finale ten books in the making. If you've traveled with Emma, Leo, Riley, and Mia from Ancient Egypt to the edge of the future, this is the journey's end. And its beginning.

Time isn't a line. It's a labyrinth.

For readers ages 10 and up. The Endless Hour is Book 10 of the Chrono Explorers series and is best enjoyed after reading Books 1 through 9.
