So as the author, I can't really "review" the story; therefore I am relaying my experience with writing it (the start and finish date actually indicate when I started writing this up until its official release).
Yes, this book was a fairly long while in the making between the original conception of the idea (which was vastly different from what it ended up becoming), to the research that went into it, the writing and revising, and finally the release. I am heavily influenced by literature that predates WW2, particularly Gothic fiction (Edgar Allan Poe, Mary Shelley). But as for contemporary influences, some of my top picks are Stephen King, Freda Warrington, and Rebekah Armusik. Anyone that can tell a good and highly complex storyline (or even storylineS) that is eventually all woven together and has a connection at the end is okay by me.
Seeing the story of The Birthrite Series evolve (and continuing doing so) has been quite a ride. During the summer that the story REALLY began to take shape into something of a real first draft (summer of 2013), I was actually reading Stephen King's IT for the third time. The overall basic theme of that book loosely influenced Descent, as did The Shining, Salem's Lot, and The Stand. At that time, I was also into the Gothic Vampire Romances of Freda Warrington's A Taste of Blood Wine and Rebekah Armusik's Gothic Memoirs series (both of which are vastly different from the teen vampire romance genre). I love a story with a theme that flirts with the darker side of the world and humanity, along with a tangled web and battles between good and evil. History and Mythology are also great interests of mine and I like longer stories because if I really enjoy a story, I want it to last.
All that takes place in this book builds up to what the rest of the series will bring. Which I look forward to bringing. :)
