Double warned: SPOILERS!
Volume 8: i didn't quite undestood what happened, but the last chapters were a hell of a ride. 100% will ship again. Also *TRIPLE WARNING* Anechka french kissed Martina. Totally worth it.
I suspect our MP has claim to monarchy that used to rule the Republic and he is playing both sides to reclaim the throne. Volume 8 is an attempt to sabotage Duchy attempt to create proxy army.
Apparentely so. Because in the end of the Volume 8 HUGE SPOILERS SERIOUSLY
Sinan is finally arrested, Martina is promoted to the rank of a Captain and is ready to be reassigned, she finally hooks up with Kirill, and the Spark movement manages to overthrow the Grand Duke and the Revolution begins.
