18-year-old Caroline already feels her life has fallen apart. She sees monsters within everyone that nobody else even knows exist. But when her old school nemesis turns up to ruin her life even further--at least, that's what Caroline thinks--actually teams up with her to defeat the evil feeling of hatred all around the world, she discovers all these other feelings within the human mind, some lovely and harmless, others that tear at a person's soul, causing permanent damage. It is up to Caroline to divide her evil world from Lukas's. She just needs some extra help.
