Thirty Days to Love or Die

A month after the wedding, Xiao Xing, heir to the marquis, is going to have his wife executed. It is written that way in a novel, and the person it falls on is Li Xunzhi, who woke up inside that book as the princess he has just married. She knows the date, so she sets about making him want her alive. A cousin in the household is working against her and the rest of the house watches her for a wrong step. She breaks up the schemes as they come, handles the crises the marquis's household runs into, and goes through the estate's account books until she can show where the money has been going. Xiao Xing thinks better of her each time. The emperor turns out to be her cousin and to have come from the same world she did, and the two of them work at the problem together. She is poisoned once and slandered more than once. A woman planted in the house by the northern tribes has been passing information out of it, and the case that closes around Xiao Xing is built out of that.
