Superstitious - R. L Stine

On the small Pennsylvania college campus Liam O'Connor cuts a dashing, romantic figure. The Irish-born professor of folklore has good looks, a sweet charm, and a host of Old World superstitions - all of which dazzle beautiful graduate student Sara Morgan. Plunging headlong into a sudden love affair, Sara barely has time to notice the dark drama unfolding on the campus. Four murders have been committed, each more gruesomely horrifying than the one before it, each committed by someone, or something, with terrible fury and strength. Suddenly Sara is receiving crank phone calls, warning her to stay away from Liam ... fearing her ex-boyfriend Chip's next angry outburst ... wondering why Liam's unmarried sister, Margaret, is so suffocatingly close to them ... and trying to escape the lecherous stares of her boss, Milton Cohn, the dean of students and the owner of a murderous-looking knife collection. When Liam proposes marriage, Sara accepts, making love by the light of sixteen candles, one of Liam's superstitions. Somehow, that final step seals her fate. The police begin to close in on a killer, the death toll mounts, and Sara is caught in an ever-tightening web. At its center, behind the most innocent superstitions, waits the greatest terror of all...
