That being said, this is insta love. And it's hard to create insta love when the two main characters have known each other for years. But of course, one shiny day, everything changes and he suddenly can't live without her. Woohoo.
I was also so annoyed with Abby. What did you THINK would happen? How did she thinks this would work? And she kept railroading Jace! Don't throw the man you love under the bus when you should've just been honest with him from the get go *sigh*.
