Crypto-Squad by Eric S. Brown and Jason Brannon is a quick fun read. Involving a host of mythological (to some) characters that form a secret government agency. Mothman, Ness, The Jersey Devil, are just some of the creature characters to look forward to.
The agency is around to deal with things that are outside what most normal people can deal with. This book deals with a group called the Unending. These people are some super powerful necromancers who have unleashed a horde of zombies and have many more tricks up their sleeves.
This is a great book for people who like paranormal action and I'm looking forward to checking out some of the other books in the series.
