Wolf Mother: The Horus Heresy Series (Unabridged‪)‬

Aboard the Molech's Enlightenment, amongst the countless civilian refugees that fled the Warmaster's invasion, a serpent makes its nest.

The Chaos cult that brought House Devine to its knees lives on, preying upon the weak and the helpless, and it falls to Alivia Sureka to root out the evil that hides in plain sight. Luckily for her, she has an ally who is more than familiar with such tactics the lone wolf Knight Errant, Severian.
