This is one of my favorite tropes!!!! Brothers best friend, sisters best friend, best friends brother, best friends sister. I am here for it! I don't know what it is about this kind of plot that gets to me. Brighton Walsh creates such great characters and she weaves a lovely story. It took me a day to read this, and that included me working a nine hour day in between reading. I'd read it all over again if I didn't want to get to the next book so bad.
