Dusk of Humanity - M K Dawn - Bog

The world has ended...
Dr. Sloan Egan never thought life after the apocalypse would be so dull.
Trapped in an underground bunker. Forced to share a room with a man she can barely stand. The top surgeons in the country fighting to suture the most insignificant of wounds.
Until Major Lee Archer wheels a mangle and dying man into her OR.
The injuries she knows how to treat. The side effects... like nothing she's seen before.
And he's not the only one infected.
The virus is spreading. Killing. Stalking its prey.
Their only chance at survival. Leave The Bunker. Face a world lost to the dead.
They are the last of humanity. Death is not an option.
