A new day has dawned. Those without the mark are considered a virus to be cleansed from the Global Union. Pets are being targeted to lead the enemy to their owners in hiding. When the students of Heaventree receive their new assignments, Cornelius questions his ability to lead a team into danger. How can he trust his teammate, Atlys, after she showed her lack of loyalty in the building challenge? And does his mentor, Mr. Deal, truly understand these end times, or is he in over his head?

Flare, Corn's sister, is growing closer to Josh, and has been tasked with protecting Heaventree's invisible dome. Can she truly use her creative gifts to keep her friends safe and the campus hidden? Filled with pet rescues, ancient books, and hidden passageways, Book 2 of the House of Heaventree series is a page-turning continuation of The Firstborn. In The Virus, war rages just beyond the walls of Heaventree, while the students battle within for faith, trust and unity.
