Crescent Earth

"You're not going to use that gun, are you? In the future you're from, have I been shot and killed today?"
Frankie Mason is dead. Even though his murderer has been caught and sentenced, Frankie's only son, James, is unable to cope with the permanent scar left by witnessing his father's brutal death. No matter what lengths he would have to go to, James will have his revenge.
Crescent Earth is the first book of this sci-fi series, opening with the first intentional murder of a human committed by a sentient android. Piloting a time traveling spaceship, James pursues his father's murderer, infiltrating Martian moon bases, breaking into solarpunk glass cities, and fighting his way through underground military facilities.
Now, as the truth of his father's murder finally seems within his reach, James is finding revenge and time travel itself a little more than he had asked for. Would he be able to carry out his plans for vengeance, even knowing he should? After all, as the mysterious Dr. Haywood Williams says, history has a way of preserving itself.
