What's the Name of That Book??? discussion

I believe that this is an Ilona Andrews short story. She did write some amazing short stories. I had it on my laptop and IPAD but can’t find it now and cannot remember the title. I did look at her website but cannot find any information
regarding this. Or even what universe she may have set the plot in. It is about a college student who is the last female descendant of a magical family that has been in a debt obligation for years with another magical family, I am not sure if only females were called to answer the obligation. I also don’t remember what caused that family to be in a debt they must always answer when they are called to help. Her mother was called years ago but is too old now so the daughter must go instead. she travels to the other family where she must assist the head male member of that family in a dangerous r race in order to win against another family of evil people to claim rights. the area for the race has been dangerously booby trapped and changed physically to a very decrepit area. The race will be televised and there will be judges. I believe the MMC’S brother died and the MMC got some affliction where magical bugs or insects appear and can kill him. His magical power is much greater than hers but she is obligated to protect him during the race. . I believe his sister was married to one of the male members of the evil family and she has children. Her ex husband is very involved in this and IS TRYING to get the children. her brother is determined to protect his niece and nephew at all costs. The FMC discusses ending her family.s obligation with the head male, he may be open to it but she STATES THAT THIS will finally end now She says she will never get married nor will ever have CHILDREN AND THAT WILL finally end her family’s debt obligation.
they are to search for a flag or something to claim in order to win. During the story, they manage to kill some of the EVIL cheating members from the other team. Near the end of the story The mmc gets injured and collapses. THE FMC sees the prize and has to climb a very unsafe shifting pile of debris. She retrieves the prize which wins the race. she ends up saving the MMC’S life AND SHE DRAGS HIM OUT OF THE AREA. He has feelings for her and visits her at college at end of story thank you.
