Cameron. Saga of the Children of the Gods, #3

After more than five centuries of eternity, watching his loved ones vanish around him, Cameron is finally freed from his punishment and wishes to return home. However, this is not his only wish. With a troubled breath, and just before being hurled into the vortex of time, he makes a wild plea: that Elenwë, the rightful daughter of the deities who sacrificed herself to right their wrongs, may live again.
Upon his return in 1416, in the Highlands, the destiny of the Only Child begins, and he will soon find himself joined by companions he would have never chosen willingly! Time is running out, for in the shadows, a God of Darkness has risen and is preparing to corrupt the world of men. Cameron is now the enemy to destroy... or to enslave.
