I loved Peace, Love, and Baby Ducks! Here is breakdown of the title/summary of the book:
Peace: When Carly comes back from a trip in the wilderness, she decides to become a more down-to-earth girl. She now wears tie-dye shirts and long, flowing skirts (which, of course, her parents don't approve of). Carly tries to break out of the norm by pretty much ditching her old friends for new, "diverse" friends. Oh, and while Carly is getting skinny and muscular on her wilderness trip, her sister Anna is getting hotter by the minute, turning her into a guy magnet.
Love: Carly has a very special relationship with Anna. They hang out all the time, even when one of them has a friend over. Carly, as the older sister, protects Anna and stands up for her. But Anna doesn't want to be Carly's little "ducky-wucky" anymore...
Baby Ducks: "Ducky-wucky" is Carly's pet name for Anna. But Anna is bigger, hotter, and more mature now. She doesn't want to be Carly's little anything right now.
Can the sisters patch up this tear in their relationship? Read Peace, Love, and Baby Ducks to Find out.
