School will be back in session starting next week for Purdue. The Siren and The Spectre might be the perfect horror book for students as the main character is - pause for dramatic effect - a Purdue professor! AHH! Written by West Lafayette High-School Teacher Jonathan Janz, this book is sure to scare you and not just with the presence/existence of the Purdue professor. West Lafayette Library Director Nick Schenkel has the review.
