Vincent shall henceforth be known as Vampire Daddy In Leather Pants. Vampire Daddy is motivated by making the world safer for his son (also wife and daughter, but they do not appear in this book) and loot. Being an otherwise uncaring creature, the methods and mindset are ruthless and very satisfying. 

The LitRPG elements don't overwhelm the story, but leveling up skills properly and choosing the right class are important concerns for everyone. There are lots of logistics, rather than the standard "make numbers bigger." Lots of action scenes, intense training, and banter.
