Protect the prince
(Book)

"First, Evie has to deal with a court full of arrogant, demanding nobles, all of whom want to get their greedy hands on her crown. As if that wasnt bad enough, an assassin tries to kill Evie in her own throne room. Despite the dangers, Evie goes ahead with a scheduled trip to the neighboring kingdom of Andvari in order to secure a desperately needed alliance. But complicating matters is the stubborn Andvarian king, who wants to punish Evie for the deaths of his countrymen during the Seven Spire massacre. But dark forces are at work inside the Andvarian palace, and Evie soon realizes that no one is safe. Worse, Evies immunity to magic starts acting in strange, unexpected ways, which makes her wonder whether she is truly strong enough to be a Winter Queen."--Publisher description.
