"Great stones crack and split. Storms will tell and the world is changed ... Seventeen-year-old Grace has found the archdruid who can teach her to use her power as the veleda--the priestess prophesied to save Ireland. But nothing is as it should be. The archdruid is a dangerous fairy, and Grace can't learn the spells, no matter how hard she tries. Something is wrong ... but what? Meanwhile, gentleman Patrick Devlin and warrior Diarmid Ua Duibhne both struggle with their love for Grace, their duty to their warring brotherhoods, and their support of Ireland. And New York City is in chaos with protests, immigrant gangs, and police crackdowns. The only hope for the future is the ancient ritual, just weeks away, in which Diarmid must take the life of the girl he loves. Secrets, legends, and prophecies collide in an explosive finale that will save the world--or destroy it"--Page 2 of cover.
