This month, Baen Books will be publishing Sister Time by John Ringo and Julie Cochrane. This sequel to Cally’s War features “the return of Michelle O’Neal, the first human Sohon mentat. This book is about life, love, and covert operations amongst the universe’s ultimate dysfunctional family. Cally O’Neal is officially dead. In her over forty years of being an active secret agent she hasn’t used her real name, much less spoken to her sister. So when Michelle interrupts an important mission, by seemingly appearing out of thin air, it’s an unexpected reunion. And leads to unexpected consequences throughout the galaxy, including not only battles with hand-held weapons, but the deployment of the deadliest machine ever invented by alien or human.”
