To watch is to protect. To protect is to serve. To serve is to fight. Working as a Watcher, the angel Calastair, does whatever it takes to protect his friends from the cruel jinn, Talock, who has been tasked to remove the memories of Tiffany and Johnathan, the only humans in their circle, because they know too much. As Reka and the others embark on a journey to a safe haven, Cal battles with the enemy. Meanwhile, Reka and Peter's relationship begins to heat up. The more time she spends with him, the more she begins to realize what a good mate he would make. But when an innocent flirtation creates a wave of jealousy, she wonders if there is more to her feelings than just choosing the right mate. Are they destined to be together, or will the struggles they face as they work to protect their friends be too much of a strain on their friendship? When Cal is injured, personal feelings are pushed aside as the group tries to find a way to help him. Seeking guidance from an array of otherworldly beings, they seek out the source of the angel's power and fight to survive along the way. Will the good guys prevail, or will evil prove to be too much for the group of young warriors?
