The asteroid, Jupiter’s Hammer, hurtles toward a future cataclysmic collision with Earth. Graduate student Jack Pierce, comes upon enigmatic, seductive Aiyanna, who has no memory. They accidentally stumble onto time travel using a strange jewelry artifact and one of Aiyanna’s Psy abilities. Who is Aiyanna, and what are the meanings of the magical tattoos appearing, morphing, and moving across her body? Where did the artifact come from, and why is Aiyanna here? In 2167, a secret government agency, in the aftermath of the asteroid collision, rushes to discover time travel, risking self-annihilation. Aiyanna and Jack are pursued by the mafia in 1980, Las Vegas; street gangs in 2014, San Diego; Homeland Security in Manhattan during the 2040’s; and time travelers from 2167. They must exploit time travel benefits and avoid its perils to deal with these threats, and to uncover the roles of Fate, and Free Will in the outcome of Jupiter’s Hammer. Will Jupiter’s Hammer smash into Earth? Can they stop it? Should they try? What will become of Aiyanna and Jack’s growing attraction?
Aiyanna and Jack are two of my favorite book characters. They really come alive as they banter back and forth during arguments, speculating, making decisions, flirting and come-ons, and anything I can’t think of just now – oh yes even having philosophical conversations about free will, fate, time travel rules (that they must discover), perception, or the nature of time itself. The minor characters, especially Ed Wickstroem in 2167 and Kathryn Lomax from Homeland Security, are also well developed, “rounded” as is said. There is not too much science in this novel, it stands on the characters, their adventures and mishaps. Much of the book has the feel of a suspense novel, i.e. what will happen next?
Jack and Aiyanna chapters are written first person, present tense from Jack’s perspective, which drives the good pace of the story. Homeland and 2167 chapters are in third person omniscient and are used to fill out details on new technology as well as having their own storylines, which relate to the main chapters for Aiyanna and Jack. There are enough twists to keep you on your toes. I was pulled into the characters, the discovery of the rules for time travel, their romance, and their story. I was invested in the outcome and very pleased with the unexpected ending. I highly recommend this book, especially to time-travel buffs.
