Shelter: Beast Invasion, Book 2 (Unabridged‪)‬

Drew successfully navigated the dangers of a Post Apocalyptic America and made it home to his family in Colorado. However, he is mortally wounded and bereft of power. Now, Drew must not only survive, but thrive. He will have to force himself to grow strong enough to protect his loved ones.

This can be considered a post-apocalyptic progression novel. It has similarities to cultivation novels, but is not Wuxia, it is only slightly Xianxia.

This is the second book in a trilogy.
