The Oathing Stone. The Rituals Trilogy, #2

Are you ready for a Faerie civil war? A race with time to save the ones you love?After a year blissfully hidden together in a small village on Ireland's lush green, Catherine and Bowen are ready to tie the knot. The joining of an ancient druid doctor and a woman blessed with druid magic from the sacred oak tree calls for nothing less than a traditional Celtic ceremony. For this, to connect them to their ancestors and the sacred place where they marry, a key item must be chosen for the ritual. The oathing stone.
Their need for discretion allows for only a gathering of Catherine's closest friends and family. But after the couple's first night together, strange and sudden events unfold. Blood mingles with fire, and Catherine's magic becomes unstable. Meanwhile, the mysterious Faerie Kings send a Fae spy to witness Catherine's magic which disrupts not only her life but her best friend Bella's when she becomes his sudden obsession.
Just after Bella goes missing, it is up to Catherine to get her back, but it is only the beginning of their problems as she finds they're embroiled in the middle of a Faerie civil war.
