i cant remember much about the book except for that. there was a girl and a boy and i guess they were against this other guy and he told them that they were brother and sister and they refused to believe it and he told her that they would figure everything out.. sorry this is really vague but its everything i can remember. i think i read it during the summer of last year. please help!

I'm guessing it's not this but in The Mortal Instruments series two of main characters are led to believe they are brother and sister by the villain.

What else happens? There has to be something more that you're neglecting to tell. For example, was this modern or historical or magical (fantasy)? Was this YA then because you call them boy and girl? About how old? Were they important people or just an average joe/jane? Do you recall any other characters? For example, another girl who annoyed you because she liked the hero too or someone who was the best friend of the brother/sister hero/heroine? Ect?

Here's the link for the first book in the Mortal Instruments series, which Jenni mentioned: City of Bones
