Evolution's Essence (Book 3 and conclusion to the Star Pirate Legends)

Oliver has to end a threat to his friends and family and manages to finally get ahead for the first time in his life.
Yet battle is a sweet release with becoming a father with his Match being a royal pain! He just wants to discover what happened to his people and Renee can't help pulling the rug out from underneath. Still, he loves her, but she has a nasty surprise for him and it involves breeding back the Solarian line and it means he'll never get a moment's rest.
Thankfully the Creelin help out.
Something out there has the answers and it'll blindside Oliver like nothing Renee could ever do no matter how mad she might get.
