The book Hive by DL Orton is a winner. We have time travel, the multiverse, a romance that spans decades, and an evil billionaire who is trying to conquer the world with his technology. There is something in this sci-fi novel for everyone, and I thoroughly enjoyed it. The couple at the center of the plot finds themselves in dire circumstances, trapped in an biosphere-like structure with a snappy AI companion that is part HAL, part Hitchhiker’s Marvin, only in much better moods. There are cameo references to that and other seminal sci-fi works to further delight readers. I won’t tell you how it ends, but the couple’s journey through multiple universes and space time is interesting, and delightful Highly recommended.
