Four books at once

I am just in from the Plympton Library with 4 books and because it is vacation, I am just going to lie on the sofa and read them all. So far, I've started The Evolution of Calpurnia Tate (Funny and a bit gross story of a girl living 100 years ago in Texas who wants to be a scientist and hangs out with her very eccentric grandfather and avoids her 5 pesty brothers); A Crooked Kind of Perfect (a girl who wants to be a famous pianist has a really really insane dad who signs her up for lessons on a cheap organ with a lady who only knows TV theme songs); Peeled (a teen murder mystery); and the Lemonade Wars (about fighting siblings who sell lemonade). I've started all of them and now have to worry about confusing the plots. Let me know if you've heard of any of these-and do check in and let me know what you are reading.
