What do you do when your beliefs are challenged?
Following the temporary alliance with Grant and Able, Raleigh and her team must find a way to defeat the evil Sigma before he strikes again. To do so they must take a perilous journey to an island off the Greek coast where an ancient tribe of healers has a secret that may be able to help them. Sealed off from the world, the order only allows those with serious illnesses to benefit from their knowledge. In order to infiltrate the group, Raleigh must fake illness by weakening herself and allowing her blackouts to return. The ruse works, but what she finds on the other side will make her question not only herself, but everything she has learned about Lucid, as well.
Will Raleigh and the Designed find the answers they need before Sigma returns to exact his vengeance?
