Hazel Lynn might be Gatekeeper between the Summer Court and the mortal realm, but thanks to a perceived betrayal, the Sidhe want nothing to do with her. Until she unearths a secret that could either place the right person on the throne of Summer… or doom the whole of Faerie to destruction. Together with her former mentor, Darrow, Hazel determines to prevent the Courts from falling into chaos. But the two vengeful faerie queens who have their sights set on the throne both need Hazel's help to win their prize. And they have the ultimate leverage: information on how Hazel might be able to free her family from enslavement to Faerie forever. As the clock ticks towards the crowning of the next monarch, the pressure builds on Hazel to find a solution and bring an end to the conflict. But the Gatekeeper's curse is irrevocably tied to the future of the faerie realm itself, and Hazel is about to find out just how deep the Sidhe's deception runs. And how much she'll have to sacrifice to save her family.
