Caught in the Middle (Sweet Valley High #42) by Francine Pascal - Vintage Paperback

Off-limits...

Sandra Bacon has finally found a boy to love. Manuel Lopez is kind, sensitive, and handsome, and he cares about Sandra as much as she cares about him.

But there is one problem: Sandy's parents don't approve of Manuel. So the couple must keep their love and their precious moments together a secret.

Then eyewitnesses place Manuel at the scene of a life-threatening accident, and only Sandy can clear his name. If she tells the truth, she may lose her parents' trust and love; but if she doesn't, she will certainly lose Manuel forever.
