Readers of the previous three books in the Raven Cycle will find immense satisfaction in this culmination of the series’ plethora of storylines. Cabeswater is being unmade from the inside by a demon, and it threatens the world Adam, Gansey, Blue, and especially Ronan find vital. Gansey finds his King at last, but it’s not the solution he believed it would be. Saving Cabeswater and his companions demands Gansey’s sacrifice, but also the strengths and abilities of friends old and new as they problem-solve under pressure in a moment of crisis. Romance that has been building since book one reaches fruition for several characters, including Gansey and Blue, who struggle to escape the fatal destiny of the foretold kiss. Reading the earlier volumes is a must to follow the complex storylines, but this masterful conclusion is a pleasure worth waiting for, and the happy ending feels well-deserved by this compelling cast of teens who are living in our world while battling threats from other planes and other times.
