An interesting book, first of the Clan Founding trilogy. Story of Andery (sic!) Kerensky finding his place among the exiled SLDF, his father and his brother intertwines with flashbacks from Amaris occupied Moscow. This book would be a 4 star, if not for using a foreign language the wrong way and sudden teleportation of A's mother from ACW Moscow straight to her grave on Eden.
Casus belli eterni in Battletech lacks the supernatural and xenophobic explanation that works for the grim dark future, and sometimes it shows in this book, but I accept that the author's hands were quite tied by already existing lore.
