Kaia, a Harpy, has been trying to convince Strider (one of the Lords of the Underworld: the Keeper of the demon Defeat) for some time that she's the woman for him, but Strider keeps giving her a wide berth. He knows that she once slept with Paris (the Keeper of Promiscuity - or, to put it bluntly, sex). It isn't the fact that Kaia once slept with his friend that bothers Strider, but rather, he fears that his demon's determination to win all challenges would demand that he outperform his extremely experienced friend... something he fears might not be possible. So regardless of how very attracted he is to Kaia, Strider would like to keep as much space between them as he can. For preference, a Continent or two.
Until he discovers that she is in an extremely dangerous position, having been co-erced into entering an ongoing series of Harpy contests - a sort of cross between Gladiators and Mortal Combat - known as the Harpy Games. And thanks to a disaster she caused years before (earning her the nickname 'Kaia the Disappointment'), Kaia is at a significant disadvantage, as nearly all of her race (including her mother) are out to get her. Obviously, Strider can't turn his back on her. Even if he has to pretend to be her consort in order to be allowed to stay with her. When they discover that the prize for winning the Games is one of the four artifacts the Lords have been seeking, it becomes clear that for both Kaia and Strider the outcome of the Games is a matter of urgency. They'll have to learn to trust and rely on each other to ensure that both of them win.
With lots of hints at potential further stories - Paris and Sienna's (upcoming), Kane, William - but no sign/mention of several previous characters, including some whose stories are far from resolved (notably Torin - the Keeper of Disease - and Cameo - the Keeper of Misery) - to say nothing of the ongoing story arc surrounding the artifacts and the Lords' battle against the Hunters, there's still plenty of life in this series.
My goodness, do Gena Showalter and her good friend Kresley Cole write in a similar fashion these days. Their styles have pretty much always been quite similar, but they're becoming more so - to the point that, had this been written as a stand-alone book rather than as part of Showalter's ongoing 'Lords of the Underworld' series, I'd have had a hard time telling whose writing I was reading. Indeed, the Harpy Games and some of the supernatural conflicts/concepts associated with them did, at times, feel strongly reminiscent of the two of Cole's Immortals After Dark series dealing with participation in supernatural games/quest 'The Talisman Hie' -
No Rest For The Wicked and
Wicked Deeds on a Winter's Night (Immortals After Dark 4).
