To make things worse, she learns that Jace does not want her there, and Simon has been thrown in prison by the Shadowhunters, who are deeply suspicious of a vampire who can withstand sunlight.As Clary uncovers more about her family's past, she finds an ally in mysterious Shadow-hunter Sebastian. With Valentine mustering the full force of his power to destroy all Shadow-hunters forever, their only chance to defeat him is to fight alongside their eternal enemies. But can Downworlders and Shadowhunters put aside their hatred to work together? While Jace realizes exactly how much he's willing to risk for Clary, can she harness her new found powers to help save the Glass City -- whatever the cost?
Love is a mortal sin and the secrets of the past prove deadly as Clary and Jace face down Valentine in the final installment of the New York Times bestselling trilogy The Mortal Instruments.
What I thought: Well once again all I have to say is WOW. I gave this one 5 stars as well. That's 5 stars for every book in the series so far. I am so glad that there is going to be a fourth book!! The way this one ends I would have been ok with it being the end of the series but I am so glad that it is not. This is a series that I don't ever want to end. I love it. I think this book made up for the relationship that I was made about in the first book. One thing that made me mad in this book was Jace was kind of a jerk to Clary. He was only acting that way to keep her safe but still he really hurt her and so did Isabelle in this book. Isabelle was looking out for Jace but she took it a little to far.
