Total Eclipse

A billionaire, a thief, and a sex robot in a miniskirt are walking around the lunar colony blackmailing and killing people.
Kate Devana, a retired Marine and Space Force Guardian, returns to find it's become the new Wild West. The powers that be don't like her much because the last time she was there, she blew the place up. But the colony's not big enough for all of them.
Can Kate stop the rogue AI without nuking the place like last time? Then again, with so much billionaire vanity in one place, maybe she should do the solar system a favor.
On the moon, Kate Devana is the law.
"A ... rip-roaring, action-packed, and perplexing near-future science fiction/crime fiction mashup. Total Eclipse presents another high-octane and complexly twisted case for Kate Devana." -- Manhattan Book Review.
"Totally enjoyable...This book has all the earmarks of what makes reading sci-fi so enjoyable-warm-hearted characters with nerves of steel and situations and conflicts that have us gripping our seats to see who will come out the winner." - The International Review of Books, Gold Badge Award
