City of Bones by Candra Clare, is it worth moving to the second book?

Ok so, I just finished the first book. Well, I have three pages left in the epilogue, but I've already scanned them over and really don’t see the point. I am unbelievably and beyond disappointment right now. Candra has a great story with lots of twist and action, but to ruin it by making the only interesting love story in the book a tale of unknowing , was just a bummer (being mild here). So now, I'm grossed out and if I ever re-read the book, I'll be really nauseated every time they make out. And what do I have to look forward too? Jace hooks up with Isabelle?--Yippy :-/ Ooo ooo, maybe Clary will fall for dependable and steady Simon-- how fun :-/ Candra has really given me no reason to move on with the series. The action was great, but it was the love that really had me interested and now that's ruined. However, I don’t want to be hasty. My decision determines what my book club reads, so I've come to you. Is this Series worth continuing? Does Clary find a love worth reading about? A simple yes or no will do with that, but not too many details. However, if it is revealed that Jace and Clary are in fact not siblings, that is one spoiler I want! I know I'm still holding onto a thread of hope here, but if there's still hope for those two to get together, let me know please! Any way, thanks for listening to my rant and telling me whether or not it's worth moving on with the books. -Rain Dancer
