Marrying the Cold hearted General

Su Yuening has managed her father's household, his accounts, and two shops since she was fourteen. She can spot a fraudulent ledger in twenty minutes. She is, by every measure, prepared for anything.
She was not prepared for her engagement to be annulled three days before the wedding.
Or for the imperial order that arrived the same evening - bestowing her as wife to Jiang Chenyu, the Iron Wall General, a man whose reputation made entire armies reroute themselves before he arrived. The capital calls it punishment. She calls it a logistical problem, packs her clay pot, and goes north.
What she finds is not what anyone warned her about: a general who has survived four assassination attempts but cannot survive her asking whether the north has good lamb. A compound of 300,000 soldiers who have reorganized their entire social hierarchy around her cat. And a conspiracy so carefully hidden that the only person who noticed it was a woman who was supposed to be decoration.
When an assassin broke into her room at the second watch, she was angrier about the clay pot he knocked over than about the assassination attempt itself.
The assassin found this deeply unsettling.
So did the General, but for entirely different reasons.
Jiang Chenyu has spent twenty-eight years being the most dangerous person in any room he enters.
Then she walked into his.
