Sera, Dak and Riq are time travelers belonging to a group called Hystorians.  They are trying to fix Breaks in time to prevent a future catastrophe.  In this novel they are sent back into ancient Mayan times.  At first they think their Infinity Ring sent them to the wrong time period, but they figure out that they needed to be there to protect the Mayan Codex.  Then they  warp to the time of the Conquistadors.  Again they save the real Codex and discover the links that connect them back to their first stop in Mayan times.
  

Each of the three time travelers has a distinct personality and set of skills.  When they work together everything goes well.  At times they clash, just as all people do.  The characters stay true to their own selves, with bits of their personalities revealed in each adventure.  The action is nonstop.  Readers will love this.  This title brings in a bit of love interest for the more mature readers.  The author provides enough detail of settings for readers to see the places in their mind’s eye.  Descriptions are detailed without taking away from the action.  The dialogue sounds genuine, not forced.
