Elizabeth's First Kiss (Sweet Valley Twins #43)

Secret crush ...Elizabeth Wakefield has known Todd Wilkins since kindergarten, but she's never noticed how cute he really is, until she sees him dancing with her sister, Jessica. Now Elizabeth can't stop thinking about him--and everywhere she goes, Todd turns up, too. Could he actually like her as much as she likes him? Elizabeth wishes she knew more about boys. But when she finally asks her twin for some advice on the subject, she makes a terrible discovery: Jessica has a crush on Todd, too!

How can Elizabeth fall for a boy that her sister already likes? There's only one honorable thing to do: forget Todd and never let Jessica know she cares. But that's not going to be such an easy thing to do...
