The Cassandra Chronicles

Hypochondriac, neurotic, and a habitual worrier, Ariel Leve has always looked on the blighted side of life.She counts it a good day if she manages to get out of bed.If someone should ask: what’s the worst that can happen? she has a ready-made list and lives in permanent fear of what’s to come.But at least, as a pessimist, she’s fully prepared for any eventuality: people who see the glass half full are only a spill away from disappointment. Whether you’ve been dumped by the love of your life, lost your job, said the wrong thing at a party, or forgotten to have children, Ariel is there to remind you that it could be worse — you could be her.
