Jennifer Estep’s Kill the Queen is joyfully tropetastic: after Lady Everleigh witnesses the massacre of everyone who stands near to the throne before her, except one traitor, she escapes due to her hidden magic and plans to disappear, becoming just plain old Evie, despite her promise to the previous queen to take back the throne. She falls in with a group of gladiators and ends up training as a gladiator herself, not noticing the parallel with the fact that the first queen of her bloodline rose to the throne via combat as a gladiator. Throughout the book, she discovers that skills she learned as the seventeenth in line to the throne are useful — things that dealt with certain customs that nobody more important had the time to cater to, like baking a particular kind of pie and learning fiendishly complex dance steps.
It continues in that vein throughout: it’s readable, and fairly well-paced, and it has all the obligatory spices like a fairly obvious deeper plot, and a hate-to-love romance. It’s basically brain candy, and there’s absolutely nothing wrong with that. I didn’t love it, and I’m not sure if I’m going to bother reading the second book or not, but it was fun.
