Waiting On Wednesday (1) City of Glass by Cassandra Clare

To save her mother's life, Clary must travel to the City of Glass, the ancestral home of the Shadowhunters -- never mind that enter-ing the city without permission is against the Law, and breaking the Law could mean death. 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 newfound powers to help save the Glass City -- whatever the cost?

March 24th guys! So excited for this, I have been waiting for so long! I'm seriously excited to read about Sebastian, I wonder if he will be Clary's new love interest? Seeing as the others didn't exactly work out...

Anyways, I seriously cannot wait for the 24th! So many books come out that day, City of Glass, Wintergirls, Something Maybe, etc. The agony of waiting is killing me.
