For the Honor of the Empire (The Honor Trilogy)

In For the Honor of the Empire, haunted by the horrors of war and the weight of her new role as envoy to the Sultan Line, Margaret Peric reaches her breaking point. With the support of her estranged mother, her devoted sister Louise, and a slowly mending bond with Markus Ackov and his daughter Jessie, she begins the long road to recovery.
Meanwhile, on the volatile alternate Earth of Sultan, Jade Carvello and her partner Carlos Babineaux uncover a terrifying plot: eco-terrorists are preparing to unleash a devastating weapon – one that could destabilize the entire Cross-Temporal Empire. As Carlos walks a dangerous line between spy craft and exposure, Jade must protect Margaret, now a symbol of diplomatic hope, as enemies close in on all sides.
When a deadly bombing rocks the Sultan capital and Margaret is taken hostage, survival becomes uncertain. The conspiracy leads back to a line thought lost to history – and to a biological weapon born from its ancient secrets.
As the Empire prepares for war, loyalties are tested, love is weaponized, and redemption comes at the highest of costs.
