Aelliana Caylon has survived her brother's attempt to kill her. Her mother, Delm Mizel, has declared her son and heir dead for his crimes. Daav yos'Phelium, Delm Korval, has taken her under his protection, now that she is able to say she does not feel safe in House Miz, el. And she and Daav are natural lifemates.
But Mizel views her simply as an asset, all the more valuable now that the heir is officially dead, and also resents her for having been the occasion of the events that caused his death. The Delm is determined to get her back and wring every bit of value out of her. Her brother's abuse of her has damaged her natural bond with Daav. And getting Ride the Luck offworld and starting a working, successful courier service is going to be even harder than she anticipated.
Nothing is made better by the fact that Daav's sister Kareen considers Daav's judgment worthless and Aelliana unfit to be associated with Clan Korval in any way. She's determined to make Aelliana publicly and spectacularly embarrass herself and Daav.
As they are both pressured by their clans, Mr. dea'Gauss works hard to negotiate a solution between Korval and Mizel, while Mizel works to achieve only one thing: getting Aelliana back under their thumb. But if that weren't enough, it also becomes clear that someone is stalking the Low Port and taking pilots. As Delm Korval, that's also Daav's problem to solve.
This is another thoroughly enjoyable Liaden adventure, mixing adventure with romance. There's enough background included that I think this can be read before the others, if this is the one you find. If you want more on what preceded the events of this story, you want to find Scout's Progress, where Daav and Aelliana meet.
I bought this book.
