Amazon is offering the Kindle version of Sixty-One Nails by Mike Shevdon for the low, low price of free.
Here’s the book description:
There is a secret war raging beneath the streets of London. A dark magic will be unleashed by the Untained… unless a new hero can be found.
Neverwhere’s faster, smarter brother has arrived. The immense SIXTY-ONE NAILS follows Niall Petersen, from a suspected heart attack on the London Underground, into the hidden world of the Feyre, an uncanny place of legend that lurks just beyond the surface of everyday life. The Untainted, the darkest of the Seven Courts, have made their play for power, and unless Niall can recreate the ritual of the Sixty-One Nails, their dark dominion will enslave all of the Feyre, and all of humankind too.
