**Oh Spirits of Love, Hear My Plea; Make Stormy Kincaid Fall in Love With Me.** Graveyards at midnight aren't really my thing, but I figured it was worth one spooky spell to make Stormy Kncaid crazy about me. I had no intention of conjuring up a ghost, really! But suddenly, there was Monday, a hunk of a teenage ghost who'd been dead for thirty years. Monday was glad I'd botched the spell, sine he had a mission of his own — to get back at his girlfriend for not mourning when he died. Maybe I'd lost my sanity, but I agreed to help. After all, Monday wasn't a typical ghost. He was into rock'n roll, not scaring people, and he was extremely easy on the eyes, even if mine were the only ones that could see him. In fact, he could almost make me forget about Stormy. But what's the sense in falling for a ghost... especially one who has to go back there in just two weeks?
