On the Razor's Edge

[b:On the Razor's Edge 16059450 On the Razor's Edge (Spiral Arm, #4) Michael Flynn https://d.gr-assets.com/books/1360343179s/16059450.jpg 21846212] is the fourth book in Flynn's Spiral Arm series. It picks up right where [b:In the Lion's Mouth 12160824 In the Lion's Mouth (January Dancer, #3) Michael Flynn https://d.gr-assets.com/books/1317794427s/12160824.jpg 17131879] ended.Bridget ban's daughter, Mearana the Harper, has left with the Shadow Ravn Olafsdottr and headed into the Confederacy. It is unclear whether she was kidnapped or went willingly. Bridget and a team of Hounds that she persuades to join her head into the Confederacy (and toward Old Earth) in pursuit. They all know that they are being lured into a war between the “Shadows of Name” and that some of their number may not return. However, Mearana must be rescued and there is rumored treasure in the form of ancient artifacts/information – it must be done.Meanwhile Mearan's father, Donovan buigh the scarred man, is being held in wily old Gidula's stronghold on old Earth. Donovan has his own tight path to walk. He fears that if he gives Gidula the knowledge of how to enter the Secret City he will not survive long; so, he has to play Gidula along while he gathers his own resources.From that start intrigues pile upon each other. Donovan goes on a journey of discovery on Old Earth. The conflict widens into a full war between the Names and their Shadows, with Bridget ban and her Hounds, Donovan, and Mearana adding extra random factors. The conflict becomes something I can only describe as a Ninja war with high-tech weapons.This is a satisfying end to the series. Although you could read this story on its on, I would recommend reading the first three books first.
