Karis' self imposed isolation from her friends after a bad break up and slight germaphobic ways is probably what saved her life. Karis uses life skills she learned as a child to stay alive, knowing how to cook from scratch and how to cook acorns so they are edible to the self defense classes her father made her take, she was even wary enough to stockpile her dogs food when the virus kept most of her coworkers home. Karis tried getting a flight out of NY after the CDC cleared her but she wouldn't, couldn't leave her dog behind. She made friends with two little girls across the courtyard and fought off the madness of the isolation and quiet the was once NYC and then she met Ollie. Oliver "Ollie" is a British citizen who arrived two weeks before the quarantine got stuck in NYC. Karis who saved his life but still unsure if she could trust him, it seemed like this virus and quarantine brought out the worst in people.
Overall, this book was outstanding. Karis is intelligent, strong, and intuitive and a great main character. Julia and Emma the little girls across the courtyard were adorable and Julia was wise beyond her years. Zeke, the dog, a great companion and a sympathetic ear. Ollie is exactly what Karis needed, at first you're unsure of him but he does earn Karis' trust and her love he kept her sane and hopeful. I loved this book it was emotional and heart-poundingly thrilling. This is in my top three for apocalyptic genre along with Z for Zachariah and The Wolf Road.
